yes I figured out the only current possible division would be to convert ft to mt - that could be run against population number as well of course.. Dividing the population number to get maps of India or China a bit less cluttered without using a specific style would be quite handy. Though yes - besides improving rules for cities not much else use of a division factor for values that I can think of. So right now only 3.28, 3.28^2, 3.28^3 and so on is possible (i did not actually check if it is possible to convert twice, but think so).
Hi Felix
I don't think there is any way to do maths on tag values.
It should not be too difficult to implement additional variable filters
that do a simple maths op with a constant, eg:
{set population='${population|divide:"7"}'}
