rounding to the nearest whole number regardless the decimal value

Looking to round a number from my formula to the nearest whole number regardless the decimal value it comes up with.  I am calculating container usage here.  If I have 200 parts and the container only holds 48 parts it will use 4.16667 containers.  So I would need my answer to be 5.

Here is my formula that I am using:

Shared NumberVar TotalNum;

Shared NumberVar BinsParts;

WhilePrintingRecords;

If {V_Part_Rel.Std_Pack_QTY}>1 then

     BinsParts :=(if (TotalNum=0) then 0

                         else (TotalNum / {V_PART_REL.std_Pack_QTY}));

When it prints on my report BinsParts will show 4.1667, I seen function using Ceiling but when I tried to put it in front of BinsParts it error out saying the remaining text does not appear to be part of the formula.

Ceiling(BinsParts,1) := continue with formula above....

Any suggestions would be helpful.

Thank you in advance.
