VGETMANTPS xmm1{k1}{z}, xmm2/m128/m32bcst, imm8    (V5+VL
__m128 _mm_getmant_ps(__m128 a, int intv, int sgn)
__m128 _mm_mask_getmant_ps(__m128 s, __mmask8 k, __m128 a, int intv, int sgn)

__m512 _mm512_maskz_getmant_round_ps(__mmask16 k, __m512 a, int intv, int sgn, int sae)

For each float, get the mantissa from (1), perform specified normalization and store the result in (2).
imm8 bit 1:0
intv		 Normalization Interval 00b _MM_MANT_NORM_1_2: 1 <= x < 2
01b _MM_MANT_NORM_p5_2: 0.5 <= x < 2
10b _MM_MANT_NORM_p5_1: 0.5 <= x < 1
11b _MM_MANT_NORM_p75_1p5: 0.75 <= x < 1.5
the mantissa is normalized to fit within the range specified.
imm8 bit 3:2
sgn		 Sign Control 00b _MM_MANT_SIGN_src: sign is unchanged
01b _MM_MANT_SIGN_zero: sign is set to positive
10b, 11b _MM_MANT_SIGN_nan: if sign of the source is negative, QNaN_Indefinite is stored as the result.
