"infinity" jargon "Jargon File (4.3.1, 29 Jun 2001)"
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.
"infinity" foldoc "The Free On-line Dictionary of Computing (27 SEP 03)"
infinity
1. The size of something infinite.
Using the word in the context of sets is sloppy, since
different infinite sets aren't necessarily the same size
cardinality as each other.

2. The largest value that can be represented in
a particular type of variable (register, memory location,
data type, whatever).
See also minus infinity.
