Expand description
Compute the approximate reciprocal of the lower half-precision (16-bit) floating-point element in b,
store the result in the lower element of dst, and copy the upper 7 packed elements from a to the
upper elements of dst.
The maximum relative error for this approximation is less than 1.5*2^-12.
