pub unsafe fn fmuladdf16(_a: f16, _b: f16, _c: f16) -> f16🔬This is a nightly-only experimental API. (
core_intrinsics)Expand description
Returns a * b + c for f16 values, non-deterministically executing
either a fused multiply-add or two operations with rounding of the
intermediate result.
The operation is fused if the code generator determines that target instruction set has support for a fused operation, and that the fused operation is more efficient than the equivalent, separate pair of mul and add instructions. It is unspecified whether or not a fused operation is selected, and that may depend on optimization level and context, for example.
