Function core::arch::x86_64::_mm512_roundscale_round_ps [−][src]
pub unsafe fn _mm512_roundscale_round_ps<const IMM8: i32, const SAE: i32>(
a: __m512
) -> __m512
This is supported on x86-64 and target feature
avx512f only.Expand description
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.
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
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter. Intel’s documentation
