_mm512_roundscale_round_ps in core::arch::x86_64 - Rust
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

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
