SCIENTIFIC CALCULATOR for ANDROID

1. What is it? SCIENTIFIC CALCULATOR for ANDROID is a scientific calculator for the Android platform.

2. Current state. For now, it is a prototype.

Current features:

• Exact computation of scientific expressions (functions of the Java Math library).
• Basic plotting.
• Auto-completion of input expressions.

Planned features:

• Better documentation.
• Testing.
• Better UI.
• Pretty print.
• Symbolic calculus.
• Possibility to program the calculator.
• Fetching programs on a repository over the web.
• Importing data for plotting, statistical computations...
• Exporting data for use with other applications...

3. How to build it? The project has been built with the Android Eclipse plugin. Here are the instructions to build it.

   • Make sure your Eclipse installation is Android-enabled.
   • Import the project.
   • Update the Reference Libraries with the CUP Runtime library in Properties > Java Build Path > Libraries > Add external JAR. The library can be found here: http://www2.cs.tum.edu/projects/cup/
   • Run!

If you are interested to work on the parsing of the expressions, you will need CUP and JFLEX. The projects can be respectively found here:

• http://www2.cs.tum.edu/projects/cup/
• http://jflex.de/ The .lex and .cup files are in com.google.calculator.parser.

4. History. 2008-03-20: Prototype. Released on Google Code.

5. Contact. This project has been started as a 20% project by Laurent Tu during his internship at Google. Feel free to contact him at tulaurent@gmail.com.
