                             UBASIC
						Ver. 8.30

   This number theory package is intended to be   useful  for
   exploratory research and for teaching.  The routines   are
   available in three implementations - TURBO PASCAL for  the
   Macintosh and for IBM compatibles, and   UBASIC   (for IBM
   compatibles).  Multiprecision arithmetic routines      are
   included for the TURBO PASCAL implementations      (UBASIC
   contains multiprecision arithmetic built-in).    There are
   about 50 number theoretic algorithms, including   routines
   for primality testing, elliptic curve factoring,   Shank's
   square form factoring, calculating continued    fractions, 
   solving systems of linear diophantine equations,   and all
   the common functions.  These are available from the author
   via anonymous   "ftp"   over the Internet, from

   in the directory pub/numbdroid.  If you have any   trouble

To those who aren't familiar with UBASIC, it is a multiprecision package
that runs on IBM PC's. It is written by the Japanese number-theorist  
Dr. Yuji Kida. A review by Prof. Walter Neumann appears in

"Computers and Matematics," May/June 1989, Vol 36, Number 5.

                              UBASIC 8.30

Version 8 of UBASIC has the high precision
real and complex arithmetic (up to 2600 digits) of previous versions,
but adds exact rational arithmetic and arithmetic of polynomials with
complex, rational, or modulo p coefficients, as well as string
handling and limited list handling capabilities.  In addition UBASIC
has context-sensitive on-line documentation (read ubhelp.doc for
information).  The file ubhelp.xxx that this uses is ASCII and can be
printed for hard copy documentation.
