Performs a floating point scale of the rounded scalar float64 elements in source a by multiplying by 2b, stores the result in the lower destination element using writemask k (the element is copied from src when mask bit 0 is not set), and copies the upper element from b to the upper destination element.

Performs a floating point scale of the rounded scalar float64 elements in source a by multiplying by 2b, stores the result in the lower destination element using zeromask k (the element is zeroed out when mask bit 0 is not set), and copies the upper element from b to the upper destination element.



_mm_scalef_sd 

extern __m128d __cdecl _mm_scalef_sd(__m128d a, __m128d b);

_mm_maskz_scalef_sd 

extern __m128d __cdecl _mm_maskz_scalef_sd(__mmask8 k, __m128d a, __m128d b);

Performs a floating point scale of the scalar float64 elements in source a using values from b, stores the result in the lower destination element using zeromask k (the element is zeroed out when mask bit 0 is not set), and copies the upper element from b to the upper destination element.



_mm_scalef_round_ss 

extern __m128 __cdecl _mm_scalef_round_ss(__m128 a, __m128 b, int  round);

Performs a floating point scale of the rounded scalar float32 elements in source a by multiplying by 2b, stores the result in the lower destination element, and copies the upper element from b to the upper destination elements.



_mm_mask_scalef_round_ss 

extern __m128 __cdecl _mm_mask_scalef_round_ss(__m128 src, __mmask8 k, __m128 a, __m128 b, int  round);

Performs a floating point scale of the rounded scalar float32 elements in source a by multiplying by 2b, stores the result in the lower destination element using writemask k (the element is copied from src when mask bit 0 is not set), and copies the upper three packed elements from b to the upper destination elements.



_mm_maskz_scalef_round_ss 

extern __m128 __cdecl _mm_maskz_scalef_round_ss(__mmask8 k, __m128 a, __m128 b, int  round);
