Synopsis
_mm512_log2ae23_ps(__m512 a);
Description
Compute the base-2 logarithm of packed single-precision (32-bit) floating-point elements in "a" with absolute error of 2^(-23) and store the results in "dst".
Operation
FOR j := 0 to 15
i := j*32
dst[i+31:i] := LOG(a[i+31:i]) / LOG(2.0)
ENDFOR
dst[MAX:512] := 0
