isgreater

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

Parameters

Return value

Nonzero integral value if x > y , ​ 0 ​ otherwise.

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 > .

Example

#include <math.h>
#include <stdio.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;
}

isgreater(2.0,1.0)      = 1
isgreater(1.0,2.0)      = 0
isgreater(INFINITY,1.0) = 1
isgreater(1.0,NAN)      = 0
