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 2N-1 -
1 but minus infinity is -
(2N-1), not
-(2N-1 - 1).
Note also that this is different from time T
equals minus infinity, which is closer to a mathematician's
usage of infinity.
