.SH DESCRIPTION
|
|
|
|
.LP
|
|
|
|
The \fIdiv\fP() function 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 integer 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 \fIdiv\fP() function shall return a structure of type \fBdiv_t\fP,
|
|
|
|
comprising both the quotient and the remainder. The
|
|
|
|
structure includes the following members, in any order:
