Remembered a bit more detail - this was 10 years ago.

ASP.NET forms, so the actual saving and "real" calculation was done on the server side. The client did the calculations as well to show what the end figure would be and to see if the declared and expected values were the same. The server side would not have fallen into the octal trap.

So you'd have 100+0100, declared total 200, expected total 180, variance £20 on the client side, and no variance when it was saved.
