Computes the quotient and remainder of a long integer.
#include <stdlib.h>
ldiv_t ldiv ( long int numer, long int denom );
| numer | Numerator | |
| denom | Denominator |
The ldiv function divides numer by denom, computing the quotient and the remainder. The sign of the quotient is the same as that of the mathematical quotient. Its absolute value is the largest integer that is less than the absolute value of the mathematical quotient. If the denominator is 0, the program will terminate with an error message.
The ldiv function is similar to the div function, with the difference being that the arguments and the members of the returned structure are all of type long int.
The ldiv_t structure, defined in STDLIB.H, contains the following elements:
| Element | Description |
| long int quot | Quotient |
| long int rem | Remainder |
The ldiv function returns a structure of type ldiv_t, comprising both the quotient and the remainder.

void 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",

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