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 using zeromask k (the element is zeroed out when mask bit 0 is not set), 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.
