LDIV(3P)                POSIX Programmer's Manual               LDIV(3P)

PROLOG

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

NAME

       ldiv, lldiv — compute quotient and remainder of a long division

SYNOPSIS

       #include <stdlib.h>

       ldiv_t ldiv(long numer, long denom);
       lldiv_t lldiv(long long numer, long long denom);

DESCRIPTION

       The functionality described on this reference page is aligned
       with the ISO C standard. Any conflict between the requirements
       described here and the ISO C standard is unintentional. This
       volume of POSIX.1‐2017 defers to the ISO C standard.

       These functions shall compute the quotient and remainder of the
       division of the numerator numer by the denominator denom.  If the
       division is inexact, the resulting quotient is the long integer
       (for the ldiv() function) or long long integer (for the lldiv()
       function) of lesser magnitude that is the nearest to the
       algebraic quotient. If the result cannot be represented, the
       behavior is undefined; otherwise, quot * denom+rem shall equal
       numer.

RETURN VALUE

       The ldiv() function shall return a structure of type ldiv_t,
       comprising both the quotient and the remainder. The structure
       shall include the following members, in any order:

           long   quot;    /* Quotient */
           long   rem;     /* Remainder */

       The lldiv() function shall return a structure of type lldiv_t,
       comprising both the quotient and the remainder. The structure
       shall include the following members, in any order:

           long long   quot;    /* Quotient */
           long long   rem;     /* Remainder */
