This evaluator can be used to perform type interpolation between int values.

Summary

Public constructors

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.
