.Sh DESCRIPTION
|
|
The
|
|
.Fn div ,
|
|
.Fn ldiv ,
|
|
.Fn lldiv ,
|
|
and
|
|
.Fn imaxdiv
|
|
functions compute the value of
|
|
.Fa numer
|
|
(the numerator) divided by
|
|
.Fa denom
|
|
(the denominator) and return the stored result in the form of the
|
|
.Fa div_t ,
|
|
.Fa ldiv_t ,
|
|
.Fa lldiv_t ,
|
|
or
|
|
.Fa imaxdiv_t
|
|

|
|
These types are structs which contain two

(the quotient) and
|
|
.Va rem
|
|
(the remainder).
