Synopsis
_mm512_mask_expm1_ps(__m512 src, __mmask16 k, __m512 a);
Description
Compute the exponential value of "e" raised to the power of packed single-precision (32-bit) floating-point elements in "a", subtract one from each element, and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 15
i := j*32
IF k[j]
dst[i+31:i] := POW(FP32(e), a[i+31:i]) - 1.0
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:512] := 0
