iMath extension for

The iMath extension to enables numeric and symbolic calculations inside a Writer document. The development of iMath was prompted by a problem which I often encountered doing calculations in my profession as a mechanical engineer. I would first begin writing out the problem on paper, putting together the necessary equations, and then turn to a spreadsheet to do the actual calculations. iMath is meant to integrate this process in a single OOo text document.

See also the CompPad project which has a similar goal, and CmathOOoCAS which adds symbolic capabilities to calc.

iMath makes use of the EQC library. Linux users will have to install this first. Windows users might need to install the Microsoft Visual C++ Redistributable Package (search for "vcredist" on the Microsoft website). Please make sure to choose matching versions according to the info below!

If your operating system can install .deb packages, have a look at my PPA.

Due to the OpenOffice/LibreOffice and Windows/Linux divide, sadly not everything works as it should. Known working configurations are:

  • iMath 2.1.0 on Ubuntu 14.04 with LO 4.2 and libeqc 1.4.13
  • iMath 2.1.0 on Windows 7x64 with LO 4.3 and MS VC++ 2010 redist
  • iMath 2.1.0 on Windows 7x64 with AOO 4.1 and MS VC++ 2010 redist
  • iMath 2.0.4 on Ubuntu 13.10 with LO 4.1 and libeqc 1.4.11
  • iMath 2.0.4 on Windows 7x64 with LO 4.1 and MS VC++ 2010 redist

Notice on upgrade to version 2.1.0

iMath was extended quite a bit in the area of analysis. Two incompatible changes were introduced:

  • The diff()-function was replaced by a differential() object
  • Integrals now recognize this differential object, e.g. int {2x differential(x)}

Consult the iMath-tour.odt, section Analysis, for details about these changes.
