# ldiv

Visual Studio 2008

Computes the quotient and remainder of a long integer.

```ldiv_t ldiv(
long int numer,
long int denom
);
```

numer

Numerator.

denom

Denominator.

## Return Value

ldiv returns a structure of type ldiv_t that comprises both the quotient and the remainder.

## Remarks

The ldiv function divides numer by denom, computing the quotient and remainder. The sign of the quotient is the same as that of the mathematical quotient. The absolute value of the quotient is the largest integer that is less than the absolute value of the mathematical quotient. If the denominator is 0, the program terminates with an error message. ldiv is the same as div, except that the arguments of ldiv and the members of the returned structure are all of type long int.

The ldiv_t structure, defined in STDLIB.H, contains long int quot, the quotient, and long int rem, the remainder.

## Requirements

Routine

ldiv

<stdlib.h>

For additional compatibility information, see Compatibility in the Introduction.

### Libraries

All versions of the C run-time libraries.

## Example

```// crt_ldiv.c

#include <stdlib.h>
#include <math.h>
#include <stdio.h>

int main( void )
{
long x = 5149627, y = 234879;
ldiv_t div_result;

div_result = ldiv( x, y );
printf( "For %ld / %ld, the quotient is ", x, y );
printf( "%ld, and the remainder is %ld\n",
div_result.quot, div_result.rem );
}
```

## Output

`For 5149627 / 234879, the quotient is 21, and the remainder is 217168`
