Function tracing::stdlib::arch::x86_64::_mm_mask_roundscale_ph

pub unsafe fn _mm_mask_roundscale_ph<const IMM8: i32>(
    src: __m128h,
    k: u8,
    a: __m128h,
) -> __m128h

🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16 #127213)

Available on x86-64 only.

Round packed half-precision (16-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 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
