The GNAT, Aonix and Intermetrix compiler not support integer/modular
numbers more then 64 bit. But I have implemented the numbers which can
allocate more then 64bit, theoreticaly up to 2_000_000_000 bits. I have
implemented operations "+", "-", "*", "/", ">" ,"<", ">=", "<=", "=",
Shift. I plan to implement "and","or" shortly. I still not strongly test
this library and interesting to do this under the real application. I'm
ready to grant free help of using this library and to listen any
suggestions. I develop it under the GNAT and now porting it to the AONIX
ObjectADA for Windows. If you want to use this library, tell me, and I'm
send it to you.
