# Infinity

/in-ˈfi-nə-tē/

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.
