**infinity n.** 1. The largest value that can be represented in a
particular type of variable (register, memory location, data type,
whatever). 2. `minus infinity': The smallest such value, not necessarily
or even usually the simple negation of plus infinity. In N-bit
twos-complement arithmetic, infinity is 2^(N-1) - 1 but minus infinity
is - (2^(N-1)), not -(2^(N-1) - 1). Note also that this is different
from "time T equals minus infinity", which is closer to a
mathematician's usage of infinity.
