*** ** * ** ***

The `Float` class wraps a value of primitive type
`float` in an object. An object of type
`Float` contains a single field whose type is
`float`.

In addition, this class provides several methods for converting a
`float` to a `String` and a
`String` to a `float`, as well as other
constants and methods useful when dealing with a
`float`.

This is a [value-based](https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/lang/doc-files/ValueBased.html)
class; programmers should treat instances that are
[equal](https://developer.android.com/reference/java/lang/Float#equals(java.lang.Object)) as interchangeable and should not
use instances for synchronization, or unpredictable behavior may
occur. For example, in a future release, synchronization may fail.

## Floating-point Equality, Equivalence,
and Comparison

The class `java.lang.Double` has a [discussion of equality,
equivalence, and comparison of floating-point values](https://developer.android.com/reference/java/lang/Double#equivalenceRelation) that is equally applicable to `float` values.

## Public constructors

### Float

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public Float (double value)
```


**This constructor is deprecated.**   

It is rarely appropriate to use this constructor. Instead, use the
static factory method `https://developer.android.com/reference/java/lang/Float#valueOf(float)` method as follows:
`Float.valueOf((float)value)`.

Constructs a newly allocated `Float` object that
represents the argument converted to type `float`.

<br />

| Parameters ||
|---|---|
| `value` | `double`: the value to be represented by the `Float`. <br /> |

### Float

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public Float (float value)
```


**This constructor is deprecated.**   

It is rarely appropriate to use this constructor. The static factory
`https://developer.android.com/reference/java/lang/Float#valueOf(float)` is generally a better choice, as it is
likely to yield significantly better space and time performance.

Constructs a newly allocated `Float` object that
represents the primitive `float` argument.

<br />

| Parameters ||
|---|---|
| `value` | `float`: the value to be represented by the `Float`. <br /> |

### Float

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public Float (String s)
```


**This constructor is deprecated.**   

It is rarely appropriate to use this constructor.
Use `https://developer.android.com/reference/java/lang/Float#parseFloat(java.lang.String)` to convert a string to a
`float` primitive, or use `https://developer.android.com/reference/java/lang/Float#valueOf(java.lang.String)`
to convert a string to a `Float` object.

Constructs a newly allocated `Float` object that
represents the floating-point value of type `float`
represented by the string. The string is converted to a
`float` value as if by the `valueOf` method.

<br />

| Parameters ||
|---|---|
| `s` | `String`: a string to be converted to a `Float`. <br /> |

| Throws ||
|---|---|
| `https://developer.android.com/reference/java/lang/NumberFormatException` | if the string does not contain a parsable number. |

## Public methods

### byteValue

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public byte byteValue ()
```

Returns the value of this `Float` as a `byte` after
a narrowing primitive conversion.

<br />

| Returns ||
|---|---|
| `byte` | the `float` value represented by this object converted to type `byte` <br /> |

### compare

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static int compare (float f1, 
                float f2)
```

Compares the two specified `float` values. The sign
of the integer value returned is the same as that of the
integer that would be returned by the call:

```
   Float.valueOf(f1).compareTo(Float.valueOf(f2))
```

<br />

<br />

| Parameters ||
|---|---|
| `f1` | `float`: the first `float` to compare. <br /> |
| `f2` | `float`: the second `float` to compare. <br /> |

| Returns ||
|---|---|
| `int` | the value `0` if `f1` is numerically equal to `f2`; a value less than `0` if `f1` is numerically less than `f2`; and a value greater than `0` if `f1` is numerically greater than `f2`. <br /> |

### compareTo

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int compareTo (Float anotherFloat)
```

Compares two `Float` objects numerically.

This method imposes a total order on `Float` objects
with two differences compared to the incomplete order defined by
the Java language numerical comparison operators (`<, <=,
==, >=, >`) on `float` values.

- A NaN is *unordered* with respect to other values and unequal to itself under the comparison operators. This method chooses to define `Float.NaN` to be equal to itself and greater than all other `double` values (including `Float.POSITIVE_INFINITY`).
- Positive zero and negative zero compare equal numerically, but are distinct and distinguishable values. This method chooses to define positive zero (`+0.0f`), to be greater than negative zero (`-0.0f`).

This ensures that the *natural ordering* of `Float` objects imposed by this method is *consistent with equals*; see [this
discussion](https://developer.android.com/reference/java/lang/Double#equivalenceRelation) for details of floating-point comparison and ordering.

<br />

<br />

| Parameters ||
|---|---|
| `anotherFloat` | `Float`: the `Float` to be compared. <br /> |

| Returns ||
|---|---|
| `int` | the value `0` if `anotherFloat` is numerically equal to this `Float`; a value less than `0` if this `Float` is numerically less than `anotherFloat`; and a value greater than `0` if this `Float` is numerically greater than `anotherFloat`. <br /> |

### doubleValue

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public double doubleValue ()
```

Returns the value of this `Float` as a `double`
after a widening primitive conversion.

<br />

##### API Note:

- This method corresponds to the convertFormat operation defined in IEEE 754.

| Returns ||
|---|---|
| `double` | the `float` value represented by this object converted to type `double` <br /> |

### equals

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean equals (Object obj)
```

Compares this object against the specified object. The result
is `true` if and only if the argument is not
`null` and is a `Float` object that
represents a `float` with the same value as the
`float` represented by this object. For this
purpose, two `float` values are considered to be the
same if and only if the method `https://developer.android.com/reference/java/lang/Float#floatToIntBits(float)`
returns the identical `int` value when applied to
each.

<br />

##### API Note:

- This method is defined in terms of `https://developer.android.com/reference/java/lang/Float#floatToIntBits(float)` rather than the `==` operator on `float` values since the `==` operator does *not* define an equivalence relation and to satisfy the [equals contract](https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)) an equivalence relation must be implemented; see [this discussion](https://developer.android.com/reference/java/lang/Double#equivalenceRelation) for details of floating-point equality and equivalence.

| Parameters ||
|---|---|
| `obj` | `Object`: the object to be compared <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if the objects are the same; `false` otherwise. <br /> |

**See also:**

- `https://developer.android.com/reference/java/lang/Float#floatToIntBits(float)`

### float16ToFloat

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static float float16ToFloat (short floatBinary16)
```

The conversion is exact; all binary16 values can
be exactly represented in `float`.

Special cases:

- If the argument is zero, the result is a zero with the same sign as the argument.
- If the argument is infinite, the result is an infinity with the same sign as the argument.
- If the argument is a NaN, the result is a NaN.

#### IEEE 754 binary16 format

The IEEE 754 standard defines binary16 as a 16-bit format, along with the 32-bit binary32 format (corresponding to the `float` type) and the 64-bit binary64 format (corresponding to the `double` type). The binary16 format is similar to the other IEEE 754 formats, except smaller, having all the usual IEEE 754 values such as NaN, signed infinities, signed zeros, and subnormals. The parameters (JLS {@jls 4.2.3}) for the binary16 format are N = 11 precision bits, K = 5 exponent bits, *E*~*max*~ = 15, and *E*~*min*~ = -14.

<br />

<br />

##### API Note:

- This method corresponds to the convertFormat operation defined in IEEE 754 from the binary16 format to the binary32 format. The operation of this method is analogous to a primitive widening conversion (JLS {@jls 5.1.2}).

| `floatBinary16` | `short`: the binary16 value to convert to `float` <br /> |

| Returns ||
|---|---|
| `float` | the `float` value closest to the numerical value of the argument, a floating-point binary16 value encoded in a `short` <br /> |

### floatToFloat16

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static short floatToFloat16 (float f)
```


The conversion is computed under the [round to nearest even rounding
mode](https://developer.android.com/reference/java/math/RoundingMode#HALF_EVEN).

Special cases:

- If the argument is zero, the result is a zero with the same sign as the argument.
- If the argument is infinite, the result is an infinity with the same sign as the argument.
- If the argument is a NaN, the result is a NaN.

The [binary16 format](https://developer.android.com/reference/java/lang/Float#binary16Format) is discussed in more detail in the `https://developer.android.com/reference/java/lang/Float#float16ToFloat(short)` method.

<br />

<br />

##### API Note:

- This method corresponds to the convertFormat operation defined in IEEE 754 from the binary32 format to the binary16 format. The operation of this method is analogous to a primitive narrowing conversion (JLS {@jls 5.1.3}).

| Parameters ||
|---|---|
| `f` | `float`: the `float` value to convert to binary16 <br /> |

| Returns ||
|---|---|
| `short` | the floating-point binary16 value, encoded in a `short`, closest in value to the argument <br /> |

### floatToIntBits

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static int floatToIntBits (float value)
```

Returns a representation of the specified floating-point value
according to the IEEE 754 floating-point "single format" bit
layout.

Bit 31 (the bit that is selected by the mask
`0x80000000`) represents the sign of the floating-point
number.
Bits 30-23 (the bits that are selected by the mask
`0x7f800000`) represent the exponent.
Bits 22-0 (the bits that are selected by the mask
`0x007fffff`) represent the significand (sometimes called
the mantissa) of the floating-point number.

If the argument is positive infinity, the result is
`0x7f800000`.

If the argument is negative infinity, the result is
`0xff800000`.

If the argument is NaN, the result is `0x7fc00000`.

In all cases, the result is an integer that, when given to the
`https://developer.android.com/reference/java/lang/Float#intBitsToFloat(int)` method, will produce a floating-point
value the same as the argument to `floatToIntBits`
(except all NaN values are collapsed to a single
"canonical" NaN value).

<br />

| Parameters ||
|---|---|
| `value` | `float`: a floating-point number. <br /> |

| Returns ||
|---|---|
| `int` | the bits that represent the floating-point number. <br /> |

### floatToRawIntBits

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static int floatToRawIntBits (float value)
```

Returns a representation of the specified floating-point value
according to the IEEE 754 floating-point "single format" bit
layout, preserving Not-a-Number (NaN) values.

Bit 31 (the bit that is selected by the mask
`0x80000000`) represents the sign of the floating-point
number.
Bits 30-23 (the bits that are selected by the mask
`0x7f800000`) represent the exponent.
Bits 22-0 (the bits that are selected by the mask
`0x007fffff`) represent the significand (sometimes called
the mantissa) of the floating-point number.

If the argument is positive infinity, the result is
`0x7f800000`.

If the argument is negative infinity, the result is
`0xff800000`.

If the argument is NaN, the result is the integer representing
the actual NaN value. Unlike the `floatToIntBits`
method, `floatToRawIntBits` does not collapse all the
bit patterns encoding a NaN to a single "canonical"
NaN value.

In all cases, the result is an integer that, when given to the
`https://developer.android.com/reference/java/lang/Float#intBitsToFloat(int)` method, will produce a
floating-point value the same as the argument to
`floatToRawIntBits`.

<br />

| Parameters ||

| Returns ||
|---|---|
| `int` | the bits that represent the floating-point number. <br /> |

### hashCode

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```

Returns a hash code for this `Float` object. The
result is the integer bit representation, exactly as produced
by the method `https://developer.android.com/reference/java/lang/Float#floatToIntBits(float)`, of the primitive
`float` value represented by this `Float`
object.

<br />

| Returns ||
|---|---|
| `int` | a hash code value for this object. <br /> |

### hashCode

```
public static int hashCode (float value)
```

Returns a hash code for a `float` value; compatible with
`Float.hashCode()`.

<br />

| Parameters ||
|---|---|
| `value` | `float`: the value to hash <br /> |

| Returns ||
|---|---|
| `int` | a hash code value for a `float` value. <br /> |

### intBitsToFloat

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static float intBitsToFloat (int bits)
```

Returns the `float` value corresponding to a given
bit representation.
The argument is considered to be a representation of a
floating-point value according to the IEEE 754 floating-point
"single format" bit layout.

If the argument is `0x7f800000`, the result is positive
infinity.

If the argument is `0xff800000`, the result is negative
infinity.

If the argument is any value in the range
`0x7f800001` through `0x7fffffff` or in
the range `0xff800001` through
`0xffffffff`, the result is a NaN. No IEEE 754
floating-point operation provided by Java can distinguish
between two NaN values of the same type with different bit
patterns. Distinct values of NaN are only distinguishable by
use of the `Float.floatToRawIntBits` method.

In all other cases, let *s*, *e*, and *m* be three
values that can be computed from the argument:

`lang="java" :
int s = ((bits >> 31) == 0) ? 1 : -1;
int e = ((bits >> 23) & 0xff);
int m = (e == 0) ?
(bits & 0x7fffff) << 1 :
(bits & 0x7fffff) | 0x800000;
`

Then the floating-point result equals the value of the mathematical
expression *s*·*m*·2^*e*-150^.

Note that this method may not be able to return a
`float` NaN with exactly same bit pattern as the
`int` argument. IEEE 754 distinguishes between two
kinds of NaNs, quiet NaNs and *signaling NaNs*. The
differences between the two kinds of NaN are generally not
visible in Java. Arithmetic operations on signaling NaNs turn
them into quiet NaNs with a different, but often similar, bit
pattern. However, on some processors merely copying a
signaling NaN also performs that conversion. In particular,
copying a signaling NaN to return it to the calling method may
perform this conversion. So `intBitsToFloat` may
not be able to return a `float` with a signaling NaN
bit pattern. Consequently, for some `int` values,
`floatToRawIntBits(intBitsToFloat(start))` may
*not* equal `start`. Moreover, which
particular bit patterns represent signaling NaNs is platform
dependent; although all NaN bit patterns, quiet or signaling,
must be in the NaN range identified above.

```
public static String toHexString (float f)
```

Returns a hexadecimal string representation of the

ASCII characters.

- If the argument is NaN, the result is the string "`NaN`".
- Otherwise, the result is a string that represents the sign and magnitude (absolute value) of the argument. If the sign is negative, the first character of the result is '`-`' (`'\u002D'`); if the sign is positive, no sign character appears in the result. As for the magnitude *m*:
  - If *m* is infinity, it is represented by the string `"Infinity"`; thus, positive infinity produces the result `"Infinity"` and negative infinity produces the result `"-Infinity"`.
  - If *m* is zero, it is represented by the string `"0x0.0p0"`; thus, negative zero produces the result `"-0x0.0p0"` and positive zero produces the result `"0x0.0p0"`.
  - If *m* is a `float` value with a normalized representation, substrings are used to represent the significand and exponent fields. The significand is represented by the characters `"0x1."` followed by a lowercase hexadecimal representation of the rest of the significand as a fraction. Trailing zeros in the hexadecimal representation are removed unless all the digits are zero, in which case a single zero is used. Next, the exponent is represented by `"p"` followed by a decimal string of the unbiased exponent as if produced by a call to `https://developer.android.com/reference/java/lang/Integer#toString(int)` on the exponent value.
  - If *m* is a `float` value with a subnormal representation, the significand is represented by the characters `"0x0."` followed by a hexadecimal representation of the rest of the significand as a fraction. Trailing zeros in the hexadecimal representation are removed. Next, the exponent is represented by `"p-126"`. Note that there must be at least one nonzero digit in a subnormal significand.

| Floating-point Value | Hexadecimal String |
| `1.0` | `0x1.0p0` |
| `-1.0` | `-0x1.0p0` |

| Parameters ||
|---|---|

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | a `String` representation of this object. <br /> |

**See also:**

- `https://developer.android.com/reference/java/lang/Float#toString(float)`

### toString

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static String toString (float f)
```

Returns a string representation of the `float`
argument. All characters mentioned below are ASCII characters.

- If the argument is NaN, the result is the string "`NaN`".
- Otherwise, the result is a string that represents the sign and magnitude (absolute value) of the argument. If the sign is negative, the first character of the result is '`-`' (`'\u002D'`); if the sign is positive, no sign character appears in the result. As for the magnitude *m*:
  - If *m* is infinity, it is represented by the characters `"Infinity"`; thus, positive infinity produces the result `"Infinity"` and negative infinity produces the result `"-Infinity"`.
  - If *m* is zero, it is represented by the characters `"0.0"`; thus, negative zero produces the result `"-0.0"` and positive zero produces the result `"0.0"`.
  - Otherwise *m* is positive and finite. It is converted to a string in two stages:
    - *Selection of a decimal* : A well-defined decimal *d*~*m*~ is selected to represent *m*. This decimal is (almost always) the *shortest* one that rounds to *m* according to the round to nearest rounding policy of IEEE 754 floating-point arithmetic.
    - *Formatting as a string* : The decimal *d*~*m*~ is formatted as a string, either in plain or in computerized scientific notation, depending on its value.

A *decimal* is a number of the form
*s*×10^*i*^
for some (unique) integers *s* \> 0 and *i* such that
*s* is not a multiple of 10.
These integers are the *significand* and
the *exponent* , respectively, of the decimal.
The *length* of the decimal is the (unique)
positive integer *n* meeting
10^*n*-1^ ≤ *s* \< 10^*n*^.

The decimal *d*~*m*~ for a finite positive *m*
is defined as follows:

- Let *R* be the set of all decimals that round to *m* according to the usual *round to nearest* rounding policy of IEEE 754 floating-point arithmetic.
- Let *p* be the minimal length over all decimals in *R*.
- When *p* ≥ 2, let *T* be the set of all decimals in *R* with length *p*. Otherwise, let *T* be the set of all decimals in *R* with length 1 or 2.
- Define *d*~*m*~ as the decimal in *T* that is closest to *m*. Or if there are two such decimals in *T*, select the one with the even significand.

The (uniquely) selected decimal *d*~*m*~
is then formatted.
Let *s*, *i* and *n* be the significand, exponent and
length of *d*~*m*~, respectively.
Further, let *e* = *n* + *i* - 1 and let
*s*~1~...*s*~*n*~
be the usual decimal expansion of *s*.
Note that *s*~1~ ≠ 0
and *s*~*n*~ ≠ 0.
Below, the decimal point `'.'` is `'\u002E'`
and the exponent indicator `'E'` is `'\u0045'`.

- Case -3 ≤ *e* \< 0: *d*~*m*~ is formatted as `0.0`...`0`*s*~1~...*s*~*n*~, where there are exactly -(*n* + *i*) zeroes between the decimal point and *s*~1~. For example, 123 × 10^-4^ is formatted as `0.0123`.
- Case 0 ≤ *e* \< 7:
  - Subcase *i* ≥ 0: *d*~*m*~ is formatted as *s*~1~...*s*~*n*~`0`...`0.0`, where there are exactly *i* zeroes between *s*~*n*~ and the decimal point. For example, 123 × 10^2^ is formatted as `12300.0`.
  - Subcase *i* \< 0: *d*~*m*~ is formatted as *s*~1~...*s*~*n*+*i*~`.`*s*~*n*+*i*+1~...*s*~*n*~, where there are exactly -*i* digits to the right of the decimal point. For example, 123 × 10^-1^ is formatted as `12.3`.
- Case *e* \< -3 or *e* ≥ 7: computerized scientific notation is used to format *d*~*m*~. Here *e* is formatted as by `https://developer.android.com/reference/java/lang/Integer#toString(int)`.
  - Subcase *n* = 1: *d*~*m*~ is formatted as *s*~1~`.0E`*e*. For example, 1 × 10^23^ is formatted as `1.0E23`.
  - Subcase *n* \> 1: *d*~*m*~ is formatted as *s*~1~`.`*s*~2~...*s*~*n*~`E`*e*. For example, 123 × 10^-21^ is formatted as `1.23E-19`.

To create localized string representations of a floating-point
value, use subclasses of `https://developer.android.com/reference/java/text/NumberFormat`.

<br />

| Parameters ||
|---|---|
| `f` | `float`: the `float` to be converted. <br /> |

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | a string representation of the argument. <br /> |

### valueOf

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static Float valueOf (String s)
```

Returns a `Float` object holding the
`float` value represented by the argument string
`s`.

If `s` is `null`, then a
`NullPointerException` is thrown.

Leading and trailing whitespace characters in `s`
are ignored. Whitespace is removed as if by the `https://developer.android.com/reference/java/lang/String#trim()` method; that is, both ASCII space and control
characters are removed. The rest of `s` should
constitute a *FloatValue* as described by the lexical
syntax rules:

> *FloatValue:*
> :   *Sign~opt~* `NaN`
> :   *Sign~opt~* `Infinity`
> :   *Sign~opt~ FloatingPointLiteral*
> :   *Sign~opt~ HexFloatingPointLiteral*
> :   *SignedInteger*
>
> *HexFloatingPointLiteral*:
> :   *HexSignificand BinaryExponent FloatTypeSuffix~opt~*
>
> *HexSignificand:*
> :   *HexNumeral*
> :   *HexNumeral* `.`
> :   `0x` *HexDigits~opt~ *`.`* HexDigits*
> :   `0X`* HexDigits~opt~ *`.` *HexDigits*
>
> *BinaryExponent:*
> :   *BinaryExponentIndicator SignedInteger*
>
> *BinaryExponentIndicator:*
> :   `p`
> :   `P`
where *Sign*, *FloatingPointLiteral*, *HexNumeral*, *HexDigits*, *SignedInteger* and *FloatTypeSuffix* are as defined in the lexical structure sections of The Java Language Specification, except that underscores are not accepted between digits. If `s` does not have the form of a *FloatValue*, then a `NumberFormatException` is thrown. Otherwise, `s` is regarded as representing an exact decimal value in the usual "computerized scientific notation" or as an exact hexadecimal value; this exact numerical value is then conceptually converted to an "infinitely precise" binary value that is then rounded to type `float` by the usual round-to-nearest rule of IEEE 754 floating-point arithmetic, which includes preserving the sign of a zero value. Note that the round-to-nearest rule also implies overflow and underflow behaviour; if the exact value of `s` is large enough in magnitude (greater than or equal to (`https://developer.android.com/reference/java/lang/Float#MAX_VALUE` + `https://developer.android.com/reference/java/lang/Math#ulp(float)`/2), rounding to `float` will result in an infinity and if the exact value of `s` is small enough in magnitude (less than or equal to `https://developer.android.com/reference/java/lang/Float#MIN_VALUE`/2), rounding to float will result in a zero. Finally, after rounding a `Float` object representing this `float` value is returned.

To interpret localized string representations of a
floating-point value, use subclasses of `https://developer.android.com/reference/java/text/NumberFormat`.

Note that trailing format specifiers, specifiers that
determine the type of a floating-point literal
(`1.0f` is a `float` value;
`1.0d` is a `double` value), do
*not* influence the results of this method. In other
words, the numerical value of the input string is converted
directly to the target floating-point type. In general, the
two-step sequence of conversions, string to `double`
followed by `double` to `float`, is
*not* equivalent to converting a string directly to
`float`. For example, if first converted to an
intermediate `double` and then to
`float`, the string  

`"1.00000017881393421514957253748434595763683319091796875001d"`  

results in the `float` value
`1.0000002f`; if the string is converted directly to
`float`, `1.0000001f` results.

To avoid calling this method on an invalid string and having
a `NumberFormatException` be thrown, the documentation
for `https://developer.android.com/reference/java/lang/Double#valueOf(double)` lists a regular
expression which can be used to screen the input.

<br />

| Parameters ||
|---|---|
| `s` | `String`: the string to be parsed. <br /> |

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/Float` | a `Float` object holding the value represented by the `String` argument. <br /> |

| Throws ||
|---|---|
| `https://developer.android.com/reference/java/lang/NumberFormatException` | if the string does not contain a parsable number. |

### valueOf

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static Float valueOf (float f)
```

Returns a `Float` instance representing the specified
`float` value.
If a new `Float` instance is not required, this method
should generally be used in preference to the constructor
`https://developer.android.com/reference/java/lang/Float#Float(float)`, as this method is likely to yield
significantly better space and time performance by caching
frequently requested values.

<br />

| Parameters ||
|---|---|
| `f` | `float`: a float value. <br /> |

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/Float` | a `Float` instance representing `f`. <br /> |
