evaluate
(float fraction, Object startValue, Object endValue)
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 * (v1 - v0),
where x0 is startValue, x1 is endValue,
and t is fraction.
Parameters
| fraction
| The fraction from the starting to the ending values |
| startValue
| The start value; should be of type int or
Integer |
| endValue
| The end value; should be of type int or Integer |
Returns
- A linear interpolation between the start and end values, given the
fraction parameter.
