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 writemask k (the element is copied from src 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:

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