.SH DESCRIPTION
|
|
.LP
|
|
These functions shall compute the quotient and remainder of the division
|
|
of the numerator \fInumer\fP by the denominator
|
|
\fIdenom\fP. If the division is inexact, the resulting quotient is
|
|
the \fBlong\fP integer (for the \fIldiv\fP() function) or
|
|
\fBlong long\fP integer (for the \fIlldiv\fP() function) of lesser
|
|
magnitude that is the nearest to the algebraic quotient. If
|
|
the result cannot be represented, the behavior is undefined; otherwise,
|
|
\fIquot\fP\ *\ \fIdenom\fP+\fIrem\fP shall equal
|
|
\fInumer\fP.
|
|
.SH RETURN VALUE
|
|
.LP
|
|
The \fIldiv\fP() function shall return a structure of type \fBldiv_t\fP,
|
|
comprising both the quotient and the remainder. The
|
|
structure shall include the following members, in any order:
|
|
.sp
|
|
.RS
|
|
.nf
|
|
|

\fBlong quot; /* Quotient */
