div — compute the quotient and remainder of an integer division
div_t div(int numer, int 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.1‐2008 defers to the ISO C standard.
The div() function 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
integer 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 div() function shall return a structure of type div_t,
comprising both the quotient and the remainder. The structure includes the
following members, in any order:
No errors are defined.
int quot; /* quotient */
int rem; /* remainder */
The following sections are informative.
