Defined in header <math.h>
#define islessgreater(x, y) /* implementation defined */
 (since 哋它亢99)

Determines if the floating-point number x is less than or greater 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 || x > y, ​0​ otherwise.

Notes

The built-in operator< and operator> for floating-point numbers may raise MYMEMORY WARNING: YOU USED ALL AVAILABLE FREE TRANSLATIONS FOR TODAY. NEXT AVAILABLE IN 07 HOURS 30 MINUTES 57 SECONDS VISIT HTTPS://MYMEMORY.TRANSLATED.NET/DOC/USAGELIMITS.PHP TO TRANSLATE MORE if one or both of the arguments is NaN. This function is a "quiet" version of the expression x < y || x > y. The macro does not evaluate x and y twice.

Example

Run this code
#include <math.h>
#include <stdio.h>
 
int main(void)
