BigInt implementation for Rakudo
This is an attempt to implement a BigInt class for Rakudo, to tide us over until Rakudo's Int class can handle arbitrary precision internally. Installing: Math::BigInt is set up as a normal Perl 6 module. However, it has rather more prerequisites than normal: 1) You must have Zavolaj installed and working. 2) You must have the BigDigits routines installed as a dynamic libbd library on your system. The BigDigits source is available from http://www.di-mgt.com.au/bigdigits.html . However, it doesn't have any provision for making and installing the needed library. Right now you need to do this by hand. I hope to provide platform independent makefiles for this at some point. 3) Right now it calls malloc, free, and strcat from libSystem. If you're on a platform other than OS X, you'll have to change this to the appropriate place to find those calls. (This is lines 15-17 in lib/Math/BigInt.pm.) Again, I hope to have a better workaround for this someday. Once all that is in place, this is easily built using the standard ufo tool: ufo make make test make install As of this writing, neither BigDigits nor Math::BigInts properly handles negative numbers. Hopefully this is a temporary limitation.
