nmbthsrc.zip contains pascal source code for a collection
of number theory programs.
nmbrthry.zip contains the msdos executable versions of the
same programs.
There is no documentation, but you should be able to determine
the purpose of a program from its name, or perhaps by looking
at the source code.
***************************************************************
gp.zip is the PARI freeware which does a lot of neat mathematical
computations, including "unlimited" sized integer arithmetic. It has
no graphing features (I don't believe), but it is quite fast. Probably
best for number theory problems.
paridoc.zip is the documentation, including a tutorial. The documentation
is in the TeX type setting program. It can be viewed as an ascii file,
but a few odd symbols will appear there. It would be much better to pass
it through TeX if possible.
