Tests if x is greater than y.
#include <math.h> int isgreater (x, y) real-floating x; real-floating y;
The isgreater macro determines whether its first argument is greater than its second argument. The value of isgreater(x, y) is equal to (x) > (y); however, unlike (x) > (y), isgreater(x, y) does not raise the invalid floating-point exception when x and y are unordered.
| x | Specifies the first value to be compared. |
| y | Specifies the first value to be compared. |
Upon successful completion, the isgreater macro returns the value of (x) > (y).
If x or y is NaN, 0 is returned.
