Template:Number of prime factors (with multiplicity)
The {{number of prime factors (with multiplicity)}} arithmetic function template returns Omega(n), number of prime factors of n (with multiplicity) (big Omega(n)) of a nonzero integer, otherwise returns an error message.
Contents
Usage
- {{number of prime factors (with multiplicity)|a nonzero integer}}
or
- {{big Omega|a nonzero integer}}
Valid input
A nonzero integer less than 1031 2 = 1062961 (validation is done by the {{mpf}} arithmetic function template).
Examples
Examples with valid input (check with https://oeis.org/A001222/b001222.txt Table of n, Omega(n) for n = 1..100000)
Unfortunately, with the transclusion of {{Number of prime factors (with multiplicity)/doc}} via the {{documentation}} template the precious limited nesting levels of templates and/or parser functions were exhausted! :-( Check {{Number of prime factors (with multiplicity)/doc}} directly to see that all the tests are successful. Fortunately, by transcluding {{Number of prime factors (with multiplicity)/doc}} directly, borrowing the minimum code needed here from the {{documentation}} template, we manage to not exhaust the limit! :-)
