Another thing I discovered about the unit cost formula

Sounds like everything works out then, cool

Sorry for reviving this topic but I found another questionable example.
scout rover: 1-1-2*1.
Up to step 8 it calculates as 1. Now at step 9 it should apply minimum cost of Reactor*2-(Reactor/2) since its speed is 2 and it is not an exemption. For fission reactor this minimum computes as 1*2-1/2 = 1.5. Where should we round it to? Based on default rounding rule each step value should round down. So it should make it as 1? Which is incorrect as scout rover costs 2. So should we round this minimum up then? It would be another exception from generic rounding rule. Or maybe I don't understand the rounding rule right. Maybe it is not the each step value calculate but every division should be rounded down. In this case the 1/2 part would be rounded to 0 and minimum would compute as 2. Which is correct.

In general I find integer math to be an archaic game design concept, best avoided in new titles.  What is SMAC's tech tree except a collection of gradually marching integer increments?  It could all be done away with, if there was some consistent regime for increasing various stats by floating point values.
