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 writemask k
(elements are copied from src when the corresponding mask bit is not set). This intrinsic essentially calculates
floor(log2(x))
for each element. Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter
