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

Determines if the floating-point number x is less than or equal to 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 MYMEMORY WARNING: YOU USED ALL AVAILABLE FREE TRANSLATIONS FOR TODAY. NEXT AVAILABLE IN 07 HOURS 07 MINUTES 12 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 operator<=.

Example

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