The read-only WebGLShaderPrecisionFormat.rangeMin
property returns the base 2 log of the absolute value of the minimum value that can be represented.
Examples
var canvas = document.getElementById("canvas");
var gl = canvas.getContext("webgl");
gl.getShaderPrecisionFormat(gl.VERTEX_SHADER, gl.MEDIUM_FLOAT).rangeMin; // 127
gl.getShaderPrecisionFormat(gl.FRAGMENT_SHADER, gl.LOW_INT).rangeMin; // 24
