Recommendable way of rounding up currency values

Question

First of all see the following problem:

SetRoundMode(rmUp) and rounding “round” values like 10, results in 10,0001.

I need to round currency values up, so 0.8205 becomes 0.83, but the SimpleRoundTo behavior displayed above is giving me some headaches.

How can I round currency values up in a safe way?

Answer 1

You can use the Ceil function:

newvalue := Ceil(oldvalue * 100) / 100;
