I am just wondering if you are able to have two functions in one cell.....

However, this is probably more complicated, as I would like to round up to
the nearest 5, rather to the nearest 10?!!!

Scenario, in my cell at the moment, I have the sum function, adding a few
columns across, giving me the answer I need. Now, in addition to this sum
function, I would also like the answer to be rounded according to the
following....

Should the amount be either 0.1 or 3.2 (ie .1 or .2), the amount be rounded
down (ie 0.0 or 3.0), and if the figures are 0.3 or 5.4 (ie .3 or .4) the
amount be rounded up to the nearest 5 (ie 0.5 or 5.5)

In addition if the amounts were .6 or .7 rounded down to the nearest 5 and
..8 or .9 rounded up to the nearest 5.

Does that make sense???

I guess the best option would possibly be an if formula? but then how do I
keep the initial sum formula as part of it all???

Any help would be very greatly appreciated!
