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

Geomview

Geomview is an interactive program for viewing and manipulating geometric objects, written by staff members of the University of Minnesota Geometry Center. It can be used as a standalone viewer for static objects or as a display engine for other programs which produce dynamically changing geometry.

Grace

Grace is a WYSIWYG 2D plotting tool for the X Window System. Grace is a point-and-click tool that allows the user to draw X-Y plots. This is the program formerly known as Xmgr.
 
A few of its features are: User defined scaling, tick marks, labels, symbols, line styles, colors. Polynomial regression, splines, running averages, DFT/FFT, cross/auto-correlation. Batch mode for unattended plotting. Hardcopy support for PostScript, FrameMaker and several image formats.

PDL online manual

Perl Data Language is an extension to perl for numerics. It allows high-speed manipulation of multidimensional data arrays and includes bindings to a lot of external libraries for data processing and representation (plotting). This manual includes both introductory documents and a command reference.
The GNU DC arbitrary precision calculator

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.
python-gnuplot Manual

A Python interface to the gnuplot plotting program. Based on an object-oriented design that allows the user much flexibility to set per-dataset options such as line styles, as well as to run multiple gnuplot sessions simultaneously. Includes a demonstration and extensive documentation strings. Now supports 3-d plots!
