🔬This is a nightly-only experimental API. (
stdarch_x86_avx512_f16
#127213)Available on (x86 or x86-64) and target feature
avx512fp16
and x86-64 only.Expand description
Extract the reduced argument of packed half-precision (16-bit) floating-point elements in a by the number of bits specified by imm8, and store the results in 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.
