-.SH DESCRIPTION
-The
-.BR div ()
-function computes the value
-\fInumerator\fP/\fIdenominator\fP and
-returns the quotient and remainder in a structure
-named \fIdiv_t\fP that contains
-two integer members (in unspecified order) named \fIquot\fP and \fIrem\fP.
-The quotient is rounded toward zero.
-The result satisfies \fIquot\fP*\fIdenominator\fP+\fIrem\fP = \fInumerator\fP.
-.P
-The
-.BR ldiv (),
-.BR lldiv (),
-and
-.BR imaxdiv ()
-functions do the same,
-dividing numbers of the indicated type and
-returning the result in a structure
-of the indicated name, in all cases with fields \fIquot\fP and \fIrem\fP
-of the same type as the function arguments.
-.SH RETURN VALUE
-The \fIdiv_t\fP (etc.) structure.
