   1. Unlimited extent of time, space, or quantity; eternity;
      boundlessness; immensity. --Sir T. More.

            There can not be more infinities than one; for one
            of them would limit the other.        --Sir W.

infinity
     
        1.  The size of something {infinite}.
     
        Using the word in the context of sets is sloppy, since
        different {infinite set}s aren't necessarily the same size
        {cardinality} as each other.
     
        See also {aleph 0}
     
        2.  The largest value that can be represented in
        a particular type of variable ({register}, memory location,
        data type, whatever).
     
        See also {minus infinity}.
