The int type in solidity uses the two's complement system, so if you accidental cast a very large uint to an int, or a negative int to a uint, you may get unexpected results..

WebThis extension modifies GLSL to expose explicit 8-bit integer, and 16-bit: integer and floating-point 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.

WebOct 1, 2024 · Those of you who have been working on desktop and console graphics long enough will remember working with fp16 math in shaders during the D3D9 era.
