# 1.27.0[−][src]Function core::arch::x86::_mm_fmsub_ss

    pub unsafe fn _mm_fmsub_ss(a: __m128, b: __m128, c: __m128) -> __m128

This is supported on x86 and target feature `fma` only.

Multiplies the lower single-precision (32-bit) floating-point elements in `a` and `b`, and subtract the lower element in `c` from the intermediate result. Store the result in the lower element of the returned value, and copy the 3 upper elements from `a` to the upper elements of the result.
