Computes the quotient and the remainder of two integer values.

div_tdiv(intnumer**,intdenom);**

Return Value

div returns a structure of type div_t, comprising the quotient and the remainder. The structure is defined in STDLIB.H.

Parameters

numer

Numerator

denom

Denominator

Remarks

The div function divides numer by denom, computing the quotient and the remainder. The div_t structure contains int quot, the quotient, and int rem, 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 terminates with an error message.

Example

/* DIV.C: This example takes two integers as command-line
 * arguments and displays the results of the integer
 * division. This program accepts two arguments on the
 * command line following the program name, then calls
 * div to divide the first argument by the second.
 * Finally, it prints the structure members quot and rem.

#include <stdlib.h>

void main( int argc, char *argv[] )
{
   int x,y;
   div_t div_result;

   x = atoi( argv[1] );
   y = atoi( argv[2] );

   printf( "x is %d, y is %d\n", x, y );
   div_result = div( x, y );
   printf( "The quotient is %d, and the remainder is %d\n",
           div_result.quot, div_result.rem );
}

Output

x is 876, y is 13
The quotient is 67, and the remainder is 5
