Function _mm256_mask_roundscale_ps

pub unsafe fn _mm256_mask_roundscale_ps<const IMM8: i32>(
    src: __m256,
    k: u8,
    a: __m256,
) -> __m256

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86 only.

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:\

• _MM_FROUND_TO_NEAREST_INT : round to nearest
• _MM_FROUND_TO_NEG_INF : round down
• _MM_FROUND_TO_POS_INF : round up
• _MM_FROUND_TO_ZERO : truncate
• _MM_FROUND_CUR_DIRECTION : use MXCSR.RC - see _MM_SET_ROUNDING_MODE
