Benchmark: Coordinate test 6

Script Preparation code:

var width = 480;
var halfWidth = width >> 1;
var invertedHalfWidth = 1 / halfWidth;

Tests:

Conditional comparison
var xPos = Math.random() * width; var xQuadLeft = xPos < halfWidth ? 0 : 1;
Bitwise comparison
var xPos = Math.random() * width; var diff = xPos ^ halfWidth; diff |= diff >> 1; diff |= diff >> 2; diff |= diff >> 4; diff |= diff >> 8; diff |= diff >> 16; diff &= ~(diff >> 1) | 0x80000000; diff &= (xPos ^ 0x80000000) & (halfWidth ^ 0x7fffffff); var xQuad = !!diff;
Other test
var xPos = Math.random() * width; var xQuad = xPos ^ halfWidth && ( !(halfWidth ^ 0) || ( (xPos / halfWidth) | 0 ) );
Other test 2
var xPos = Math.random() * width; var xQuad = xPos == width ? 1 : ( ( xPos * invertedHalfWidth ) | 0 );
Other test 3
var xPos = Math.random() * width; var xQuad = xPos == width ? 1 : ~~( xPos * invertedHalfWidth );
Other test 4
var xPos = Math.random() * width; var xQuad = ~~( xPos * invertedHalfWidth );
If test
var xPos = Math.random() * width; var xQuadLeft = 0; if( xPos >= halfWidth ) xQuadLeft = 1;
If test 2
var xPos = Math.random() * width; if( xPos < halfWidth ) var xQuadLeft = 0; else var xQuadLeft = 1;
