you can either work with operations that handle fixed point, or simple multiply everything for 100 before hand
x1=20
x2=40
res=50%
20/40 = 0 (as 0.5 doesn't compute)
(20*100) / (40) = 50 %
remember the % symbol already represents the /100
you should check for zero before the division, otherwise you will see the red text exploding on your screen if you ever change the balance
anything/0 = error
you don't need this testCode:(lt, ":addorsub", 50),

Handling float calculation is something you need to learn in any language, even MBScript. Just google for it and check the discussions, like in
http://stackoverflow.com/questions/20788793/c-how-to-calculate-a-percentageperthousands-without-floating-point-precision
or check wikipedia
but if you want to learn about this you should actually search for a math book (Knuth is a great reference)
Fixed it: for other people struggling
(needs WSE)Calculates friendly and enemy troops, adds a small number to hostile because you dont now exact numbers.
Then makes a two decimal ratio of it
adding 150 troops for siege, is for My siege system, in my mod For Rome
