Round a number up to certain significant figures

[alicarlos13]

Maybe this is more of a mathematical question than Python. How can I amend the 2nd argument in upperRound such that the value returned from it for maxValue=1234 is bigger than Maximum value/4=308.5, as is the result if applied in this situation?

Basically I want this script to be fully automated other than the maxValue being input by human, so for any maxValue/4, the output from upperRound should be bigger.

What you know have in the code is awkward, in the upperRound. I would just use

 print math.ceil(a)
