It doesn't need to be very complex. I want to do some simple calculations. I 
wonder how KSpread does that, it parses "=A1+(2*A2)" to calculate the value 
of a cell based on other values. I need exactly something like that which can 
do the basic six mathematical calculations.

For my purposes an integer would be precise enough, I'm just multiplying 
(always towards integers) and adding/substracting stuff. 

If you need to know why.. most rent values in the Monopoly game are based on a 
baserent and a multiplier and/or addition based on number of improvements, 
dice thrown or properties owned. I could put about 200 static values in a 
config file, but those can actually be replaced with about 10 generic 
mathematical ones and 25 exceptions, which are mathematical rules applied 
after the generic one.
