translate-domain

OOP based numeric domain/range translation.

import TranslateDomain from 'translate-domain';

// Establish Domain Ranges
const basicDomain = new TranslateDomain([0, 100], [0, 1]);
const nonZeroBased = new TranslateDomain([100, 200], [1, 2]);
const macroDomain = new TranslateDomain([0, 1], [0,500]);

// Perform Operations
assert.equal( basicDomain.translate(50), .5)
assert.equal( basicDomain.invert(50), .5)

assert.equal( nonZeroBased.translate(150), 1.5)
assert.equal( nonZeroBased.invert(150), 1.5)

assert.equal( macroDomain.translate(.50), 250)
assert.equal( macroDomain.invert(.75), 500-(500/4))
