Classification
AVX-512, Miscellaneous, CPUID Test: AVX512_FP16
Header File

Instruction
VGETEXPPH xmm, xmm
Synopsis
 _mm_getexp_ph(__m128h a);
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.
Operation
FOR i := 0 to 7
	dst.fp16[i] := ConvertExpFP16(a.fp16[i])
ENDFOR
dst[MAX:128] := 0
