WebGLShaderPrecisionFormat.precision

The read-only WebGLShaderPrecisionFormat.precision property returns the number of bits of precision that can be represented.

For integer formats this value is always 0.

Examples

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

gl.getShaderPrecisionFormat(gl.VERTEX_SHADER, gl.MEDIUM_FLOAT).precision; // 23
gl.getShaderPrecisionFormat(gl.FRAGMENT_SHADER, gl.LOW_INT).precision; // 0
