Expand description
Convert the exponent of the lower half-precision (16-bit) floating-point element in b to a half-precision
(16-bit) floating-point number representing the integer exponent, 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 7
packed elements from a to the upper elements of dst. This intrinsic essentially calculates floor(log2(x))
for the lower element.
