ldiv, lldiv
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 ldiv, lldiv.
Computes the quotient and remainder of two integers as one operation.
Syntax
ldiv_t ldiv(
long numer,
long denom
);
lldiv_t lldiv(
long long numer,
long long denom
);
Parameters
numer
Numerator.
denom
Denominator.
Return Value
ldiv returns a structure of type ldiv_t that comprises both the quotient and the remainder. lldiv returns a structure of type lldiv_t that comprises both the quotient and the remainder.
Remarks
The ldiv and lldiv functions divide numer by denom, and thereby compute 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 and lldiv are the same as div, except that the arguments of ldiv and the members of the returned structure are all of type long, and the arguments of lldiv and the members of the returned structure are of type long long.
The ldiv_t and lldiv_t structures are defined in <stdlib.h>.

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
