🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16 #127213)

Available on (x86 or x86-64) and target feature avx512fp16 and x86 only.

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
