It is unfortunate that Perl does not have native 64-bit support (i.e. "long long"), as many compilers are adding this.

That being said, what you are doing is functional, but since the Math::BigInt library does not appear to be optimized that well, it will be slow. This may be because the library is intended to work on very big numbers, much larger than 64 bit.

If speed were an issue, a quick bit of Inline::C would certainly help.
