*************************************************************************

 Routines to do Big Number Arithmetic. These are multi-precision, unsigned
 natural numbers (0, 1, 2, ...).

 Released to the public domain by Clifford Rhodes, June 15, 1995, with
 no guarantees of any sort as to accuracy or fitness of use.

 Each int in the Big Number array will hold a digit up to MODULUS - 1.
 Choosing 10000 makes testing easy because each digit contains 4 decimal
 places.

 The Big Number is contained in a structure that has a length, nlen, and
 an array, n[], of unsigned shorts to hold the 'digits'. The most
 significant digit of the big number is at n[0]. The least significant
 digit is at n[nlen - 1];

 *************************************************************************

 The Amiga 68k/PPC version comes with both, makefiles for 68k and PPC,
 and test programs for both CPUs.

 Note, that the test program doesn't seem to do anything useful as
 far as user interaction is concerned: it just tests its internal
 routines and then waits for a key to be pressed.

 (Originally it would have run in an endless loop, but due to a missing
  kbhit() function it's now just a single loop.)

 If someone has need for large unsigned numbers (or likes to extend
 this to signed numbers) - well...
