abs function
int abs ( int n );
long abs ( long n );
<cstdlib>

Absolute value

Returns the absolute value of parameter n ( /n/ ).

Parameters

n
Integral value.

Return Value

The absolute value of n.

Portability

In C, only the int version exists.

Example

/* abs example */
#include <stdio.h>
#include <stdlib.h>

int main ()
{
  int n,m;
  n=abs(23);
  m=abs(-11);
  printf ("n=%d\n",n);
  printf ("m=%d\n",m);
  return 0;
}

Output:


n=23
m=11
