Implementing FMA and Finding Bugs in C and Rust Standard Libraries
FMA's bugs in Rust and musl libc involve important fixes and testing processes for engineers.
The incorrect implementation of fused multiply-add (FMA) in Rust and musl libc has led to significant bugs. FMA is crucial for accurate computations, allowing only one rounding error instead of two, which is essential for algorithms like trigonometric functions. The author undertook various tests and fixes to address these issues.
