Inverse Lerp Node
Description
Returns the linear parameter that produces the interpolant specified by input T within the range of input A to input B.
Inverse Lerp is the inverse operation of the Lerp Node. It can be used to determine what the input to a Lerp was based on its output.
For example, the value of a Lerp between 0 and 2 with a T value of 1 is 0.5. Therefore the value of an Inverse Lerp between 0 and 2 with a T value of 0.5 is 1.
