Probably Easy - Negative numbers

I'm having a total mind stall here...

what is the easiest number to force a whole number...what i mean is, if a number is negative it will drop the negative sign.

If there is a relatively easy way to fix this, i'd love to find out.
thanks

VB Code:

No = Abs(No)

Use the Abs function (Absulote)

VB Code:

Dim iNum as Integer
iNum = -18
iNum = Abs(iNum) 'Return 18

Damn x-posting...:)
