imaxabs

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at imaxabs.

Calculates the absolute value of an integer of any size.

Syntax

intmax_t imaxabs(  
   intmax_t n   
);  

Parameters

n
Integer value.

Return Value

The imaxabs function returns the absolute value of the argument. There is no error return.

Note

Because the range of negative integers that can be represented by using intmax_t is larger than the range of positive integers that can be represented, it's possible to supply an argument to imaxabs that can’t be converted. If the absolute value of the argument cannot be represented by the return type, the behavior of imaxabs is undefined.

Requirements

Routine Required header
imaxabs <inttypes.h>

For additional compatibility information, see Compatibility.

Libraries

All versions of the C run-time libraries.

Example

// crt_imaxabs.c  
// Build using: cl /W3 /Tc crt_imaxabs.c  
// This example calls imaxabs to compute an  
// absolute value, then displays the results.  
  
#include <stdio.h>  
#include <stdlib.h>  
#include <inttypes.h>  
  
int main(int argc, char *argv[])  
{  
   intmax_t x = LLONG_MIN + 2;  
  
   printf("The absolute value of %lld is %lld\n", x, imaxabs(x));  
}  
The absolute value of -9223372036854775806 is 9223372036854775806
