isless

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

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

-

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 <stdio.h>
-#include <math.h>
- 
-int main(void)
-{
-    printf("isless(2.0,1.0)      = %d\n", isless(2.0,1.0));
-    printf("isless(1.0,2.0)      = %d\n", isless(1.0,2.0));
-    printf("isless(INFINITY,1.0) = %d\n", isless(INFINITY,1.0));
-    printf("isless(1.0,NAN)      = %d\n", isless(1.0,NAN));
- 
-    return 0;
-}

Possible output:

-
isless(2.0,1.0)      = 0
-isless(1.0,2.0)      = 1
-isless(INFINITY,1.0) = 0
-isless(1.0,NAN)      = 0
