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.
This intrinsic essentially calculates floor(log2(x)) for each element. Exceptions can be suppressed
by passing _MM_FROUND_NO_EXC in the sae parameter
