Pretty much everything has a limit, either imposed by the software or by
the environment. Binary multiples are the most common - 16, 32, 64,
128, 256 (each less 1) often are max points since programming languages
use binary deep down. So, 256 less 1 = 255 in this case. 32768 less 1
= 32767, your value example. The environment limits include memory
capacity and hard drive space.
