unlerp

Opposite of lerp; gets the range between a lower and upper bound.

var range = require('unlerp')

//result is typically between 0.0 and 1.0
var result = range(0, 50, 25) //=> 0.5

//if you want to saturate to 0.0 - 1.0
result = require('clamp')(result, 0, 1)

The result is not clamped.

Usage

range(min, max, value)

Produces the normalized range of value between two bounds. Equivalent to:

(value - min) / (max - min)
