DIV(3C-SVR4)        RISC/os Reference Manual         DIV(3C-SVR4)



NAME
     div, ldiv - compute the quotient and remainder

SYNOPSIS
     #include <stdlib.h>

     div_t div (int numer, int denom);

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

DESCRIPTION
     div computes the quotient and remainder of the division of
     the numerator numer by the denominator denom.  This function
     provides a well-defined semantics for the signed integral
     division and remainder operations, unlike the
     implementation-defined semantics of the built-in operations.
     The sign of the resulting quotient is that of the algebraic
     quotient, and, if the division is inexact, the magnitude of
     the resulting quotient is the largest integer less than the
     magnitude of the algebraic quotient.  If the result cannot
     be represented, the behavior is undefined; otherwise, quo-
     tient * denom + remainder will equal numer.

     div returns a structure of type div_t, comprising both the
     quotient and remainder:

          typedef struct div_t {
               int  quot;     /*quotient*/
               int  rem; /*remainder*/
          } div_t;

     ldiv is similar to div, except that the arguments and the
     members of the returned structure (which has type ldiv_t)
     all have type long int.
