normalize

Normalize a number from its current range into a value between 0 and 1.

Similar: constrain, normalize, remap, lerp.

function normalize(x, r, R)
// x: a number
// r: lower bound of current range
// R: upper bound of current range

const xmath = require('extra-math');


xmath.normalize(20, 0, 50);
// → 0.4

xmath.normalize(-10, 0, 100);
// → -0.1
