isunordered

Defined in header <math.h> 
#define isunordered(x, y) /* implementation defined */
-		 (since C99)

Determines if the floating point numbers x and y are unordered, that is, one or both are NaN and thus cannot be meaningfully compared with each other.

-

Parameters

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

Return value

Nonzero integral value if either x or y is NaN, ​0​ otherwise.

-

Example

#include <stdio.h>
-#include <math.h>
- 
-int main(void)
-{
-    printf("isunordered(NAN,1.0) = %d\n", isunordered(NAN,1.0));
-    printf("isunordered(1.0,NAN) = %d\n", isunordered(1.0,NAN));
-    printf("isunordered(NAN,NAN) = %d\n", isunordered(NAN,NAN));
-    printf("isunordered(1.0,0.0) = %d\n", isunordered(1.0,0.0));
- 
-    return 0;
-}

Possible output:

-
isunordered(NAN,1.0) = 1
-isunordered(1.0,NAN) = 1
-isunordered(NAN,NAN) = 1
-isunordered(1.0,0.0) = 0
