_mm512_roundscale_pd in core::arch::x86 - Rust
Description: Round packed double-precision (64-bit) floating-point elements in a to the number of fraction bits specified by imm8, and store the results in dst. 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

[−][src]

    pub unsafe fn _mm512_roundscale_pd(a: __m512d, imm8: i32) -> __m512d

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512f` only.

Round packed double-precision (64-bit) floating-point elements in a to the number of fraction bits specified by imm8, and store the results in dst.
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
