Rascal, the Advanced Scientific CALculator, is a platform independent modular calculator. Based on modules for integer, doubles, strings, vectors and matrices it can be easily extended with existing C or C++ code.

Read the

• sample automatically generated User Documentation (html) (pdf) for Rascal to see examples of what already very basic modules can do,
• Frequently Asked Questions, also known as FOP,
• or the Module Guide (pdf) on how to create own modules.

Currently available modules and data types are:

• Generic:
  • Integer
  • Double
  • String
  • Vector and Matrix
  • Functions
• Long Integer (big numbers)
• Fraction
• Long Integer Fractions
• Complex
• Polynomials
• Taylor (Automatic Differentiation)
• C-XSC++
  • (highly accurate) long Real
  • (highly accurate) Interval, long Interval
• C-XSC++ Toolbox

Rascal is a GPLed Open Source project and hosted at Source Forge. (CVS not maintained as long there are no other developers.)
You are welcome to participate, the current goals are:

• Front-Ends for various GUI
• Additional Modules
• Improvement of parser
• Enhancement of scripting language

The current version is 0.3.2. Have a look at the changes. You can download

• the current source release of Rascal (~238kb),
• a full featured binary rpm rpm built on RedHat (~761kb),
  • including the c-xsc intervals, multi precision arithmetics as well as all other modules
  • gnome front end "grascal"
• or a light binary rpm rpm built on RedHat (~170kb)
  • with just the absolute basic modules.
  • gnome front end "grascal"
• Note that the binaries are being installed into /usr/local/bin, so check that this directory is in your path.

• the full featured online version 0.3.2 of Rascal.
