Extract the reduced argument of the lower half-precision (16-bit) floating-point element in b by the number of bits specified by imm8, store the result in the lower element of dst, and copy the upper 7 packed elements from a to the upper elements of dst.
Rounding is done according to the imm8 parameter, which can be one of:
