Math.abs-vs-bitwise (v18)

Revision 18 of this benchmark created on

Description

Checking performance differences between Math.abs and using Bitwise manipulation.

Setup

var nums = [];
      
      for (var i = 0; i < 200; i++) {
        var rand = Math.random()
        var isNegative = Math.random() < 0.5
        nums.push(isNegative ? rand : -rand)
      }
