🔬This is a nightly-only experimental API. (
stdarch_x86_avx512
#111137)Available on (x86 or x86-64) and target feature
avx512dq
and x86-64 only.Expand description
Extract the reduced argument of the lower single-precision (32-bit) floating-point element in b by the number of bits specified by imm8, store the result in the lower element of dst, and copy the upper element from a. to the upper element of dst. 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
: useMXCSR.RC
- see_MM_SET_ROUNDING_MODE
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
