From The Collaborative International Dictionary of English v.0.44 [gcide]: Countable \Count"a*ble\ (-?-b'l), adjective Capable of being numbered. From WordNet (r) 2.0 [wn]: countable adjective: that can be counted; "countable sins"; "numerable assets" [syn: {denumerable}, {enumerable}, {numerable}] From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]: countable A term describing a {set} which is {isomorphic} to a subet of the {natural numbers}. A countable set has "countably many" elements. If the isomorphism is stated explicitly then the set is called "a counted set" or "an {enumeration}". Examples of countable sets are any {finite} set, the {natural numbers}, {integers}, and {rational numbers}. The {real numbers} and {complex numbers} are not [proof?]. (1999-08-29) |
