is-multiple-of

Floating point modulus operator functionality for javascript. Accurate to 16 digits and 6 decimal places.

Rationale

• javascript can't divide floats accurately: i.e. 4.55 / .05 === 90.999999

4.55 % .05 === 0         // false

whereas:

multipleOf(4.55, .05)     // true

Installation

• Node Module

$ npm install @tecfu/is-multiple-of

• Browser

import multipleOf from 'https://cdn.jsdelivr.net/gh/tecfu/is-multiple-of/dist/is-multiple-of.esm.js'
