WebMar 28, 2016 · Precision of int and float Data Types¶. Most programming languages define the range of values that can be stored in a specific data type. For example, an “int” in Java can store values in the range -2,147,483,648(-2 31) to 2,147,483,647 (2 31-1).GLSL let’s you pick from three different precision levels for the basic data types.

It also aliases existing float, double, int, and uint types with more explicit type names. This extension can be used together with GL_KHR_vulkan_glsl extension to: enable these types to be used in a high-level language for the Vulkan API. tsh048
