🔬This is a nightly-only experimental API. (

)Available on x86-64 only.
Expand description
Scale the packed half-precision (16-bit) floating-point elements in a using values from b, and store the results in dst.
Rounding is done according to the rounding parameter, which can be one of:
_MM_FROUND_TO_NEAREST_INT
|_MM_FROUND_NO_EXC
: round to nearest and suppress exceptions_MM_FROUND_TO_NEG_INF
|_MM_FROUND_NO_EXC
: round down and suppress exceptions_MM_FROUND_TO_POS_INF
|_MM_FROUND_NO_EXC
: round up and suppress exceptions_MM_FROUND_TO_ZERO
|_MM_FROUND_NO_EXC
: truncate and suppress exceptions_MM_FROUND_CUR_DIRECTION
: useMXCSR.RC
