.SH NAME
integer: Iceil, Ifloor, min, max \- integer functions
.XE "abs,"
.XE "abs,"
.SH SYNOPSIS
.PP
.B short Iceil (a, b)
.PP
.B short Ifloor (a, b)
.PP
.B int min (b, c)
.PP
.B int max (b, c)
.PP
.B long a;
.br
.B int b, c;
.SH DESCRIPTION
.PP
The
.I Iceil
function
returns the smallest short integer which, when multiplied by
.IR b,
is not less than
.I a. 
.PP
The
.I Ifloor
function
returns the largest short integer which, when multiplied by
.I b,
is not greater than
.I a. 
.PP
For both
.I Iceil
and
.I Ifloor
if
.I b
is equal to 0 or 1,
the long integer
.I a
is truncated to a short and returned.
Otherwise, if the result is greater than a short, it is truncated
before being returned.
.PP
The
.I min
function
returns the minimum of the two integers.
.PP
The
.I max
function
returns the maximum of the two integers.
