WebGLShaderPrecisionFormat: rangeMin property

Note: This feature is available in Web Workers.

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

Examples

js
const canvas = document.getElementById("canvas");
const gl = canvas.getContext("webgl");

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