Synopsis
 _mm512_maskz_getmant_ps(__mmask16 k, __m512 a, _MM_MANTISSA_NORM_ENUM interv, _MM_MANTISSA_SIGN_ENUM sc);
Description
Normalize the mantissas of packed single-precision (32-bit) floating-point elements in "a", and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set). This intrinsic essentially calculates "±(2^k)*|x.significand|", where "k" depends on the interval range defined by "interv" and the sign depends on "sc" and the source sign. [getmant_note]
Operation
FOR j := 0 to 15
	i := j*32
	IF k[j]
		dst[i+31:i] := GetNormalizedMantissa(a[i+31:i], sc, interv)
	ELSE
		dst[i+31:i] := 0
	FI
ENDFOR
dst[MAX:512] := 0
