LDIV(3P) POSIX Programmer's Manual LDIV(3P)
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.
ldiv, lldiv — compute quotient and remainder of a long division
#include <stdlib.h>
ldiv_t ldiv(long numer, long denom);
lldiv_t lldiv(long long numer, long long denom);
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.
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 */
