Enum values
CEILING
public static final RoundingMode CEILING
Rounding mode to round towards positive infinity. For positive values
this rounding mode behaves as UP
, for negative values as
DOWN
.
Rule: x.round() >= x
DOWN
public static final RoundingMode DOWN
Rounding mode where the values are rounded towards zero.
Rule: x.round().abs() <= x.abs()
FLOOR
public static final RoundingMode FLOOR
Rounding mode to round towards negative infinity. For positive values
this rounding mode behaves as DOWN
, for negative values as
UP
.
Rule: x.round() <= x
HALF_DOWN
public static final RoundingMode HALF_DOWN
Rounding mode where values are rounded towards the nearest neighbor. Ties are broken by rounding down.
HALF_EVEN
public static final RoundingMode HALF_EVEN
Rounding mode where values are rounded towards the nearest neighbor. Ties are broken by rounding to the even neighbor.
HALF_UP
public static final RoundingMode HALF_UP
Rounding mode where values are rounded towards the nearest neighbor. Ties are broken by rounding up.
UNNECESSARY
public static final RoundingMode UNNECESSARY
Rounding mode where the rounding operations throws an ArithmeticException for the case that rounding is necessary, i.e. for the case that the value cannot be represented exactly.
UP
public static final RoundingMode UP
Rounding mode where positive values are rounded towards positive infinity
and negative values towards negative infinity.
Rule: x.round().abs() >= x.abs()
