Big Integer module

[Johannes]

This is the first complete release of my BigInt module for thinBasic.

All functionality that was in the thinBasic include script is present, along with functions to control conversion between ASCII strings and Big Integers.

Apart from the module DLL the zip file contains a small text file that explains how to get things started, a thinBasic script that tests all keywords and performs integrity checks, and a PDF manual. That manual is what makes the zip file so big, the original OpenOffice document is only 40 kBytes uncompressed.


Future developments

• Internal addition, subtraction and multiplication are still in standard PowerBASIC. I will convert these to assembler which should speed up most operations.
• Some optimisations will certainly be added for BigInt_Prm and BigInt_Cmb. I will check the other functions to see if they can be optimised as well.
• Binary logic (and, or, etc.) and bit stream (set, clear, shift, rotate, etc.) functions will be added. Descriptions of these functions are already in the manual.

If you have any questions or bug reports, or if you have suggestions for new or expanded functions, or would like to see some aliases added (e.g. BigInt_DivideWithRemainder for BigInt_DivRem), create a topic for it in this subforum and I'll see what I can do.
