Expand description

Convert the exponent of each packed half-precision (16-bit) floating-point element in a to a half-precision (16-bit) floating-point number representing the integer exponent, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set). This intrinsic essentially calculates `floor(log2(x))` for each element.
