Available on (x86 or x86-64) and target feature
f16c
and x86-64 only.Expand description
Converts the 4 x 32-bit float values in the 128-bit vector a
into 4 x
16-bit half-precision float values stored in the lowest 64-bit of a 128-bit
vector.
Rounding is done according to the imm_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
