fast-math

Faster equivalent of Math library.

Installation

$ npm install fast-math

Quick start

var FastMath = require('fast-math');
 
FastMath.abs(-123);

Covering for Math library

Currently the library implements below methods:

• abs(x),
• ceil(x),
• floor(x),
• round(x) - FastMath fixing negative number bad cases like FastMath.round(-1.5) = -2, in Node Math.round(-1.5) = -1 :(
• sign(x)

Performance

Run performance test to see how that library is fast.
