VRCPPH ymm, ymm
Synopsis
_mm256_rcp_ph(__m256h a);
Description
Compute the approximate reciprocal of packed half-precision (16-bit) floating-point elements in "a", and store the results in "dst". The maximum relative error for this approximation is less than 1.5*2^-12.
Operation
FOR i := 0 to 15
dst.fp16[i] := (1.0 / a.fp16[i])
ENDFOR
dst[MAX:256] := 0
