Subject: Re: Best Way to Round Up?
1. You probably want to use CEIL, as others have suggested.
2. The simplest way to do it with ROUND is probably
t3 = round(total + 0.5);
3. However, you have to pay attention to boundary cases. How will my
formula in #2 behave when TOTAL is an integer? Your code will leave T3 as
a missing value since it does not handle T2=TOTAL.
4. If negative values of TOTAL are possible, you may not want to use CEIL.
It depends on whether "up" means up in magnitude or up toward zero.
