Because not rounded KK is lesser number. It's like "k" Look:
11 210 000 = 11 210k = 11,210kk (not rounded) = 11kk(rounded)
So You will have to use rounded in higher level, where this 0,210kk will mean nothing.
Hey there! That's Kongregate's decision. You can increase the game size by pressing CTRL and +, though, and the game should adapt to fit the new size! [-fex]
