Function core::arch::x86_64::_mm256_roundscale_pd
source · pub unsafe fn _mm256_roundscale_pd(a: __m256d, const IMM8: i32) -> __m256d🔬This is a nightly-only experimental API. (
stdsimd #48556)Available on (x86 or x86-64) and target feature
avx512f,avx512vl and x86-64 only.Expand 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
