Template:Dedekind psi

From OeisWiki
Jump to: navigation, search
The following documentation is located at Template:Dedekind psi/doc.

The {{Dedekind psi}} arithmetic function template returns the Dedekind psi function of () of a nonzero integer, otherwise returns an error message.

Usage

{{Dedekind psi|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/A001615/b001615.txt Table of n, psi(n) for n = 1..10000)

Unfortunately, with the transclusion of {{Dedekind psi/doc}} via the {{documentation}} template the precious limited nesting levels of templates and/or parser functions were exhausted! :-( Check {{Dedekind psi/doc}} directly to see that all the tests are successful. Fortunately, by transcluding {{Dedekind psi/doc}} directly, borrowing the minimum code needed here from the {{documentation}} template, we manage to not exhaust the limit! :-)
