pub fn _mm_mask_roundscale_ps(src: __m128, k: __mmask8, a: __m128, IMM8: i32) -> __m128

Round packed single-precision (32-bit) floating-point elements in a to the number of fraction bits specified by imm8, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
Rounding is done according to the imm8[2:0] parameter, which can be one of:\
