(since C99) | |
Determines if the floating point number x is greater than the floating-point number (y), without setting floating-point exceptions.

[edit] Parameters
| x | - | floating point value |
| y | - | floating point value |
[edit] Return value
Nonzero integral value if x > y, 0 otherwise
[edit] Notes
The built-in operator> for floating-point numbers may set FE_INVALID if one or both of the arguments is NaN. This function is a "quiet" version of operator>.
[edit] Example
Run this code
#include <stdio.h> #include <math.h> int main(void) { printf("isgreater(2.0,1.0) = %d\n", isgreater(2.0,1.0)); printf("isgreater(1.0,2.0) = %d\n", isgreater(1.0,2.0)); printf("isgreater(INFINITY,1.0) = %d\n", isgreater(INFINITY,1.0)); printf("isgreater(1.0,NAN) = %d\n", isgreater(1.0,NAN)); return 0; }
Possible output:
isgreater(2.0,1.0) = 1 isgreater(1.0,2.0) = 0 isgreater(INFINITY,1.0) = 1 isgreater(1.0,NAN) = 0
