Euler a compact computational software.

Euler is a computational software with a GUI for real and complex numbers and
matrices and is capable of interval arithmetic. It can visualize
functions in two and three dimensions.

Euler is quite compact and compares favorably in speed with other free
softwares in its class like Octave and Scipy.


The current version installed in my Ubuntu 9.10 Karmic Koala is at 1.61.0.
If you have a different version of Linux, it may be available as a package
or if you prefer to install from sources, is available at
http://euler.sourceforge.net.

When you invoke Euler from Applications/Science you wil be greeted with the
following screen which allows you enter commands.





Euler as a calculator
If you type an expression Euler will echo the computed answer unless you end the
expression with a semicolon.

For example, typing sin(pi) ended with the Enter key will print the answer 1. However,
sin(pi); will just be silent.
