Inline call syntax:
| #include <simdmath.h> | 
| #include <islessd2.h> | 
| vector unsigned long long _islessd2(vector double x, vector double y); | 
| Parameters | |
| x | input vector | 
| y | input vector | 
The islessd2 function returns a vector in which each element indicates if the corresponding element of x is less than the corresponding element of y. These functions correctly compare subnormal values.
Special cases:
If either element is NaN, the comparison is false.
| ULLONG_MAX | if the element of x is less than the corresponding element of y. | 
| 0 | otherwise. |
