Welcome to mpFormulaPy!

The mpFormulaPy library provides a comprehensive set of real and complex functions in multiprecision arithmetic. For a subset of functions there is also support for decimal and interval arithmetic. mpFormulaPy is based on the Python runtime and the mpmath library, both of which implement multiprecision arithmetic. Additional planned functionality includes integration in Microsoft Excel (Windows) and LibreOffice Calc (Windows, Mac OSX, GNU/Linux), with multiprecision support for the numerical functions of these spreadsheet programs. The current version is 0.1, alpha1 (pre-release), and much of the planned functionality is still missing.

Manual

The manual is also available separately as pdf file: mpFormulaPy.pdf.

Quick start under Windows

System requirements: Windows (Desktop) with .NET Framework 4.x (Full).

Download the ZIP file and unzip it into a directory for which you have write access. Within the unzipped directory double-click on mpFormula.bat. This will start the Python Console of the SharpDevelop IDE. To confirm that mpFormulaPy is working, type the following within the Python Console:

>>> from mpFormulaPy import *
>>> pi
mpf('3.141592653589793238462643402')
>>>

Still in the Sharpdevelop IDE, click on Tools -> mpFormulaPy Manual, to open the manual in your default pdf viewer.

Within the manual, navigate to Getting Started - Tutorials, and follow the examples. You can copy and paste the Python code of the examples from the manual into the Python Console.

Quick start with Microsoft Excel (Windows)

To use the mpFormulaPy functions from within Excel, you need to install the mpFormulaPy add-in for Excel: Within Excel open the Add-Ins dialogue. Click on Browse, and navigate to the mpFormulaPy directory. Within this directory, open the mpNum directory, and select mpFormula32.xll or mpFormula64.xll, matching your version of Excel (32 bit or 64 bit).

Quick start with LibreOffice Calc (Windows, Mac OSX, GNU/Linux)

To use the mpFormulaPy functions from within LibreOffice Calc, you need to install the mpFormulaPy add-in for LibreOffice (see the manual, appendix B, for details).
