# Interface WebGLShaderPrecisionFormat

The **`WebGLShaderPrecisionFormat`** interface is part of the WebGL API and represents the information returned by calling the WebGLRenderingContext.getShaderPrecisionFormat() method.

[MDN Reference](https://developer.mozilla.org/docs/Web/API/WebGLShaderPrecisionFormat)

interface WebGLShaderPrecisionFormat {  
    [precision](#precision): number;  
    [rangeMax](#rangemax): number;  
    [rangeMin](#rangemin): number;  
}
