Babel plugin for float equal

babel-plugin-float-equal

Babel plugin for float equal

Why

0.1 + 0.2 === 0.3
// => false

WTF!?!?? Because there is rounding error.

Use this plugin.

0.1 + 0.2 === 0.3
// => true

In many cases, this one is more convenient. However, you should avoid using floating point numbers.

Install

$ npm install --save-dev babel-plugin-float-equal

Usage

.babelrc

{
  plugins: ["float-equal"]
}

Example

0.1 + 0.2 === 0.3

      ↓ ↓ ↓ ↓ ↓ ↓

typeof (0.1 + 0.2) === 'number' && typeof 0.3 === 'number'
  ? Math.abs(0.1 + 0.2 - 0.3) < Number.EPSILON
  : 0.1 + 0.2 === 0.3
