open fun evaluate(
    fraction: Float,
    startValue: Int!,
    endValue: Int!
): Int!

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 Int!: The start value; should be of type int or Integer
endValue Int!: The end value; should be of type int or Integer
Return
Int! A linear interpolation between the start and end values, given the fraction parameter.
