numbers

integers, real numbers, exact rational numbers, algebraic numbers, p-adic numbers, complex numbers,

modular integers

integers modulo n,

polynomials

and rational functions,

power series,

binary quadratic forms,

matrices, vectors,

and lists,

character strings,

and recursive combinations of these.

-emacs

GP can be run in an Emacs shell (see GP User's manual for details). This flag is then required for smooth interaction with the relevant Emacs package (pari.el). It is set automatically by the pari.el package, and will produce nice display oddities if you set it outside of an Emacs session.

-f

Fast start (or factory settings). Do not read .gprc (see below) upon startup.

-q

Quiet mode. Don't print headers or history numbers, don't say goodbye.

-p primelimit

Upon startup, GP computes a table of small primes used in most number-theoretic applications. If primelimit is set here, include primes up to that bound instead of the default. Unreasonably high values will considerably increase startup time. Exceedingly small values will cause some number-theoretic functions to fail with the message "not enough precomputed primes".

-s stacksize

Size of GP internal stack. The stack is increased from within GP in case of need but might interrupt an important computation. If your machine can stand it, start with a bigger stack (especially if you make heavy use of linear algebra). Not that computations with a smaller stack may be more efficient due to better data locality. Sensible computations should need less than 20MB.

-test

run GP in test mode: suppress printing of history numbers and wrap long output lines (to get readable diff output). For benches only.

?

to get online help.

??

to get extended online help (more precisely, to call the external help program, gphelp by default)

quit

(or \q), or EOF (Ctrl-D) to quit gp.

The following works only when gp was linked with GNU readline library:

arrow keys

for editing and viewing the input history.

TAB

for automatic completion

gp

main executable

$HOME/.gprc

(or $GPRC if set) read at beginning of execution by each gp shell. A default gprc gprc.dft is provided with the distribution. If this file cannot be found, /etc/gprc is checked instead.

pari.log

default logfile (can be changed in .gprc or interactively using default() )

pari.ps

default psfile used for postscript output (as above)

/usr/local/bin/gphelp

default external help program (as above)

/usr/local/lib/pari/pari.el

elisp package to run pari in an Emacs shell. Must be loaded from your .emacs file.

*.gp

gp programs

$GPRC

place to look for the user's gprc file (before $HOME/.gprc, ./gprc, and /etc/gprc in this order).
