Looking for numeric sort (was Simon Davey)

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Greetings programmers, I am looking for a module which implements a fast integer sorting algorithm for large lists like the Shell (as in the oil company) sort or the Quick sort. Any pointers appreciated! Thank you all.

The sort builtin is implemented using Quicksort up to Perl 5.6.1; in 5.8 it has been switched to a stable Mergesort, and using physgreg's idiom will do what you want faster than any module written in Perl itself is ever likely to achieve. Makeshifts last the longest.	[reply]

The internal perl sort command can be used to sort numerically: `@sorted_list = sort {$a<=>$b} @unsorted_list` [download] The <=> operator returns 0 if the two numbers are equal, -1 if $a<$b and 1 if $a>$b. Hope that helps.	[reply] [d/l]

Shell sort wasn't named after the oil company, but after mister Shell. Abigail	[reply]

It's very similar to the monte sort, but works with peas instead of cards. But it's still limited to only three objects. -- Tommy Too stupid to live. Too stubborn to die.	[reply]
