Expand description

Extract the reduced argument of packed half-precision (16-bit) floating-point elements in a by the number of 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 parameter, which can be one of:

Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
