#[target_feature(enable = "avx512fp16")]
pub fn _mm512_mask_getmant_round_ph(src: __m512h, k: __mmask32, a: __m512h, NORM: _MM_MANTISSA_NORM_ENUM, SIGN: _MM_MANTISSA_SIGN_ENUM, SAE: i32) -> __m512h
Normalize the mantissas of packed half-precision (16-bit) floating-point elements in a, and store
the results in dst using writemask k (elements are copied from src 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 norm and the sign depends on sign and the source sign. Exceptions can be suppressed by passing _MM_FROUND_NO_EXC
in the sae parameter
The mantissa is normalized to the interval specified by interv, which can take the following values:
_MM_MANT_NORM_1_2 // interval [1, 2)
_MM_MANT_NORM_p5_2 // interval [0.5, 2)
_MM_MANT_NORM_p5_1 // interval [0.5, 1)
_MM_MANT_NORM_p75_1p5 // interval [0.75, 1.5)
The sign is determined by sc which can take the following values:
_MM_MANT_SIGN_src // sign = sign(src)
_MM_MANT_SIGN_zero // sign = 0
_MM_MANT_SIGN_nan // dst = NaN if sign(src) = 1
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter
