Synopsis
_mm512_getmant_ps(__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". 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.
