Joona Aalto 0349809420 Add libm feature to bevy_math (#11238) ... # Objective Different platforms use their own implementations of several mathematical functions (especially transcendental functions like sin, cos, tan, atan, and so on) to provide hardware-level optimization using intrinsics. This is good for performance, but bad when you expect consistent outputs across machines. [`libm`](https://github.com/rust-lang/libm) is a widely used crate that provides mathematical functions that don't use intrinsics like `std` functions. This allows bit-for-bit deterministic math across hardware, which is crucial for things like cross-platform deterministic physics simulation. Glam has the `libm` feature for using [`libm` for the math](d2871a151b/src/f32/math.rs (L35)) in its own types. This would be nice to expose as a feature in `bevy_math`. ## Solution Add `libm` feature to `bevy_math`. We could name it something like `enhanced-determinism`, but this wouldn't be accurate for the rest of Bevy, so I think just `libm` is more fitting and explicit.		2024-01-06 22:01:57 +00:00
