Instruction
VGETEXPPS ymm, ymm
Synopsis
_mm256_getexp_ps(__m256 a);
Description
Convert the exponent of each packed single-precision (32-bit) floating-point element in "a" to a single-precision (32-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 j := 0 to 7
i := j*32
dst[i+31:i] := ConvertExpFP32(a[i+31:i])
ENDFOR
dst[MAX:256] := 0
