- Asymptote User Manual
(package: asymptote-doc)
- This document describes the Asymptote system and programming language.

- Calc
(package: calc)
- An advanced calculator and mathematical tool for Emacs.
This is an advanced calculator and mathematical tool for GNU
Emacs. XEmacs has calc built-in, so you only need this package if you
are using GNU Emacs. Very roughly based on the HP-28/48
series of calculators, calc's many features include:
* Choice of algebraic or RPN (stack-based) entry of calculations.
* Arbitrary precision integers and floating-point numbers.
* Arithmetic on rational numbers, complex numbers (rectangular and
polar), error forms with standard deviations, open and closed
intervals, vectors and matrices, dates and times, infinities,
sets, quantities with units, and algebraic formulas.
* Mathematical operations such as logarithms and trigonometric functions.
* Programmer's features (bitwise operations, non-decimal numbers).
* Financial functions such as future value and internal rate of return.
* Number theoretical features such as prime factorization and
arithmetic modulo M for any M.
* Algebraic manipulation features, including symbolic calculus.
* Moving data to and from regular editing buffers.
* "Embedded mode" for manipulating Calc formulas and data directly
inside any editing buffer.
* Graphics using GNUPLOT, a versatile (and free) plotting program.
* Easy programming using keyboard macros, algebraic formulas,
algebraic rewrite rules, or extended Emacs Lisp.
- The GNU DC arbitrary precision calculator
(package: dc)
- GNU dc is a reverse-polish desk calculator which supports unlimited
precision arithmetic. It also allows you to define and call macros.
Normally DC reads from the standard input; if any command arguments are
given to it, they are filenames, and DC reads and executes the contents
of the files instead of reading from standard input. All normal output
is to standard output; all error messages are written to standard error.
