Faster floating point math with Rust’s new API
↗
Engineers can now instruct the Rust compiler to use performance optimizations like SIMD instructions for floating-point operations, significantly closing the speed gap with integer math. This provides explicit control over the trade-off between execution speed and numerical precision.

Compilers default to conservative optimization for floating-point math because changing the order of operations can alter results due to non-commutativity.
Starting in version 1.98, Rust introduces a new API that permits the compiler to apply further optimizations to floating-point code.
Using the new API enables the use of SIMD instructions for floating-point operations, reducing the performance penalty compared to integer math.
