function

llabs

long long int llabs (long long int n);

Absolute value

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

This is the long long int version of abs.

Parameters

n: Integral value.

Return Value

The absolute value of n.

Example

/* llabs example */
#include <stdio.h>      /* printf */
#include <stdlib.h>     /* llabs */

int main ()
{
  long long int n,m;
  n=llabs(31558149LL);
  m=llabs(-100000000LL);
  printf ("n=%lld\n",n);
  printf ("m=%lld\n",m);
  return 0;
}

Output:


n=31558149
m=100000000

Data races

Concurrently calling this function is safe, causing no data races.

Exceptions (C++)

No-throw guarantee: this function throws no exceptions.

If the result cannot be represented as a long long int (such as llabs(LLONG_MIN) in an implementation with two's complement signed values), it causes undefined behavior.
