Integer Division

Integer Division

[jsanchor]

Hi guys, I have a question. It is so simple that it seems stupid. I was doing
a simple arithmetic operation 10/3. Now, I want the INTEGER division to
return the next whole number (i.e. 4). I know in floating_point type they
have an attribute called 'Ceiling. What about integer types? Currently, I am
doing a division operation B := A/3, & then  a 'rem' operation if A rem 3 /=
0 then B = B + 1; Is there a nicer method?

Thank you in advance.
Sincerely,
Jay S.

If you work with positive numbers,

   B := (A + 2) / 3;

will do the job (and (A+(D-1))/D in general).
