Q: Will iMath work in LibreOffice on Windows platform?
A: Yes, the current version of iMath (from 2.0.0 upwards) now works on the Windows platform. Note that MS Visual C++ 2010 redistributable is required for it to work properly.
Q: Is it possible to make definitions using "," instead of "."?
A: No, because the "," is also used to separate arguments to commands. But if your locale is set accordingly, iMath will convert the "." to a "," automatically when printing your formulas
Q: How do I include a *.imath file in the document?
A: Go to File->Properties->User defined properties->Include file *.imath, or use this line in iFormula %%ii READFILE {"*.imath"}. For example, if you have created 1.imath file in some directory, after READFILE the full path must be given. Here are examples of proper lines under Windows and Ubuntu.
Windows: %%ii READFILE {"C:/Document/1.imath"}
Ubuntu: %%ii READFILE {"/home/user/Documents/1.imath"}
Q: There is nothing under File->Properties->User defined properties, why is that?
A: This happens while working on a new document, the user defined properties will appear after saving that document and reloading it.
Q: Is it possible to clear only chosen equations?
A: You can clear equations by label (select it and choose Edit - Clear from the menu), or use this line in a formula %%ii DELETE{#equation_label#}. A list of labels is also possible.
Q: The iFormula and standard formula are placed differently from the left margin, is there a fast way to unify them?
A: There is no fast way to do this. Each formula would have to be manually edited. This happens because the standard formula is created with 2mm left margin (right-click -> Object to see these margins), while iFormula is created with 0mm margin.
Q: I have an equation x = 100 m. How do I tell iMath that the value is in meters?
A: In the new iFormula dialog write this x=100 "m" . The "m" tells iMath that the value is in meters. This will only work if you have included the units.imath file with File->Properties->User defined properties->Include file units.imath
Q: How do I hide an equation?
A: Select the formula and choose iMath->Edit->Hide/show , alternatively put * after EQDEF.
Q: Is it possible to hide units after evaluation?
A: Yes, in evaluation formula use NUMVAL instead of VAL.
Q: It's such a hassle to type differential(x) all the time. Can't this be shorter, like d(x)?
A: Just define a short-cut function yourself, e.g.
%%ii FUNCTION {{expand}, d, y_{_y_}}
%%ii @3@ FUNCDEF* d(y_{_y_}) = differential(y_{_y_})
