isgreaterequal

Header: <math.h>

Determines if the floating-point number x is greater than or equal to the floating-point number y, without setting floating-point exceptions.

# Declarations

#define isgreaterequal(x, y) /* implementation defined */

(since C99)

# Parameters

x: floating-point value
y: floating-point value

# Return value

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

# Notes

The built-in operator>= for floating-point numbers may raise 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("isgreaterequal(2.0,1.0)      = %d\n", isgreaterequal(2.0, 1.0));
    printf("isgreaterequal(1.0,2.0)      = %d\n", isgreaterequal(1.0, 2.0));
    printf("isgreaterequal(1.0,1.0)      = %d\n", isgreaterequal(1.0, 1.0));
    printf("isgreaterequal(INFINITY,1.0) = %d\n", isgreaterequal(INFINITY, 1.0));
    printf("isgreaterequal(1.0,NAN)      = %d\n", isgreaterequal(1.0, NAN));
 
    return 0;
