Adding 3.6, 4.4, and 5.8: Keeping the Sum 13.8

[Frank66]

just a simple question:
having to round up the following numbers:

3.6 +
4.4 +
5.8 = 13.8

I could do this:

4.0 +
4.0 +
6.0 = 14.0

but wanting to keep the sum?

In general, to be accurate, don't round until after you've finished the arithmetic.
