But that's not a very good thing to compare. What does it tell you? That C is faster than Perl for a very specific case of tight loops and integer arithmetic that is rendered totally moot by the existence of a trivial O(1) algorithm.
What it doesn't tell you is whether Perl, Inline::C, PDL, or this VB-inspired DLL is a good choice for any real-world problem. It does not implement an interesting algorithm, so you can't compare which provides the most readable implementation; and it does not benchmark an interesting calculation, so you can't really compare performance either.

Snippets of code should be wrapped in

tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
