# Function fmuladdf16

Source

    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.
