WebGLShaderPrecisionFormat.rangeMax

The read-only WebGLShaderPrecisionFormat.rangeMax property returns the base 2 log of the absolute value of the maximum value that can be represented.

Examples

var canvas = document.getElementById('canvas'); 
var gl = canvas.getContext('webgl');

gl.getShaderPrecisionFormat(gl.VERTEX_SHADER, gl.MEDIUM_FLOAT).rangeMax; // 127
gl.getShaderPrecisionFormat(gl.FRAGMENT_SHADER, gl.LOW_INT).rangeMax; // 24
