open fun evaluate(
fraction: Float,
startValue: Number!,
endValue: Number!
): Float!
This function returns the result of linearly interpolating the start and end values, with fraction representing the proportion between the start and end values. The calculation is a simple parametric calculation: result = x0 + t * (x1 - x0), where x0 is startValue, x1 is endValue, and t is fraction.
| Parameters | |
|---|---|
fraction |
Float: The fraction from the starting to the ending values |
startValue |
Number!: The start value; should be of type float or Float |
endValue |
Number!: The end value; should be of type float or Float |
| Return | |
|---|---|
Float! |
A linear interpolation between the start and end values, given the fraction parameter. |
