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
[CX] 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 IEEE Std 1003.1-2001 (“POSIX.1”) 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 */
ERRORS
No errors are defined.

CHANGE HISTORY
First released in Issue 4. Derived from the ISO C standard.
Issue 6
The lldiv () function is added for alignment with the ISO/IEC 9899:1999 (“ISO C99”) standard.
