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"}'}

( mkgmap:country=CHN | mkmgap:countrz=CN | mkgmap:country=IND |
^^
mkgmap:country=IN ) & ( place=city | place=island | place=town | place=village ) & population=* {set population='${population}/7'}
Did not work. I intend to divide the population in cities in China and India because otherwise cities clutter up the map there (also in India they do not use admin level ... which could be an alternative).
