Expand description
Round packed single-precision (32-bit) floating-point elements in a to the number of fraction bits specified by imm8, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
Rounding is done according to the imm8[2:0] 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
