Expand description
Extract the reduced argument of packed double-precision (64-bit) floating-point elements in a by the number of bits specified by imm8, and store the results in 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 // use MXCSR.RC; see _MM_SET_ROUNDING_MODE
