DIV(3) Linux Programmer's Manual DIV(3)

NAME
       div,  ldiv, lldiv, imaxdiv - compute quotient and remainder of an inte‐
       ger division

SYNOPSIS
       #include 

       divt div(int numerator, int denominator);
       ldivt ldiv(long numerator, long denominator);
       lldivt lldiv(long long numerator, long long denominator);

       #include 

       imaxdivt imaxdiv(intmaxt numerator, intmaxt denominator);

   Feature Test Macro Requirements for glibc (see featuretestmacros(7)):

       lldiv():
           XOPENSOURCE >= 600 || ISOC99SOURCE ||
           POSIXCSOURCE >= 200112L;
           or cc -std=c99

DESCRIPTION
       The div() function computes the value numerator/denominator and returns
       the quotient and remainder in a structure named divt that contains two
       integer  members  (in  unspecified order) named quot and rem.  The quo‐
       tient is rounded toward  zero.   The  result  satisfies  quot*denomina‐
       tor+rem = numerator.

       The ldiv(), lldiv(), and imaxdiv() functions do the same, dividing num‐
       bers of the indicated type and returning the result in a  structure  of
       the  indicated  name, in all cases with fields quot and rem of the same
       type as the function arguments.

RETURN VALUE
       The divt (etc.) structure.

CONFORMING TO
       SVr4, 4.3BSD, C89. C99.  The functions lldiv() and imaxdiv() were added
       in C99.

EXAMPLE
       After

               divt q = div(-5, 3);

       the values q.quot and q.rem are -1 and -2, respectively.
