FixedMathSharp Wiki

Welcome. This wiki explains the choices and behavioral contracts behind FixedMathSharp. Use the API reference when you need an exact signature; use these pages when you need to understand why an API behaves the way it does.

Start here

New to the library? Follow Getting Started. The shortest path is:

dotnet add package FixedMathSharp

using FixedMathSharp;

Fixed64 tick = Fixed64.One / 60;
Vector3d movement = new Vector3d(6, 0, 2) * tick;

For Unity, install from the dedicated FixedMathSharp-Unity repository.
