Prototype

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

Description

Divides two longs, returning quotient and remainder.

ldiv divides two longs and returns both the quotient and the remainder as an ldiv_t type. numer and denom are the numerator and denominator, respectively.

The ldiv_t type is a structure of longs defined in stdlib.h as follows:

typedef struct {

long int quot; /* quotient */

long int rem; /* remainder */

} ldiv_t;

Return Value

ldiv returns a structure whose elements are quot (the quotient) and rem (the remainder).

Example

 /* ldiv example */
 #include <stdlib.h>
 #include <stdio.h>
 int main(void)
 {
    ldiv_t lx;
    lx = ldiv(100000L, 30000L);
   printf("100000 div 30000 = %ld remainder %ld\n", lx.quot, lx.rem);
    return 0;
 }
