Default Re: Could someone explain:

I understand that but I don't see how that applies to the argument. Your saying 255 systems takes up X amount of space if you use 8 bit numbers, then you say 16 bit numbers takes up much more than 2X the space.

Your argument hold true if your talking about the number of POSSIBLE combinations, not what the actual memory requirement is. The memory requirement is linear with byte size if you keep the same number of variables for the system, the possible combinations is exponential with byte size since you have twice the number of bits, you have as you said, a lot more combinations.

But we're not talking about combinations, we're talking about straight storage, right? Or did I miss the point entirely?

so it's not just twice as much, the difference in bits is 16 - 8 = 8, so it is 2 to the 8th times as much

and 70 mb is of course the maximum, if you actually have 65536 systems in a map
