iMath extension for LibreOffice

The iMath extension to LibreOffice (and Apache OpenOffice) 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 Office text document.

Download and installation

iMath can be downloaded from sourceforge. You might also want to have a look at the CompPad project, and CmathOOoCAS which adds symbolic capabilities to calc. Both of these projects appear to be unmaintained, though.

Up to version 2.1.4, 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 2.1.4 on Ubuntu 16.04 with LO 5.1 and libeqc 1.4.18
• iMath 2.1.4 on Ubuntu 14.04 with LO 4.2 and libeqc 1.4.18 (Note: use the libginac2 .oxt package)
• iMath 2.1.4 on Windows 7x64 with LO 5.1 and MS VC++ 2013 redist
• iMath 2.1.4 on Windows 7x64 with AOO 4.1 and MS VC++ 2013 redist
