recursion (countable and uncountable, plural recursions)

- 1852, William Hastings Macaulay, chapter XIX, in Kathay: A Cruise in the China Seas[1]:
- The inhabitants predicate the recursion of these storms by numerous other signs, and are prompt to take every precaution to avoid their effects.

- n! = n × (n ? 1)! (for n > 0) or 1 (for n = 0) defines the factorial function using recursion.
- 1988, Andrew Radford, Transformational grammar: a first course, Cambridge, UK: Cambridge University Press, page 128:
- However, we have still not achieved our goal of devising a finite set of rules which will generate an infinite set of sentence structures. In order to achieve this goal, we need to allow for the fact that natural languages typically have the property that they allow potentially infinite recursion of particular structures.
- (programming) The invocation of a procedure from within itself.
- This function uses recursion to compute factorials.
