Expand description
Round packed double-precision (64-bit) floating-point elements in a to the number of fraction bits specified by imm8, and store the results in dst.
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
