Jaxe equations syntax

Author: Damien Guillaume

Jaxe has a specific equation editor, to add and change equations. An equation is edited in a text area, while the corresponding image is displayed above in real time. The equation images are saved in a folder called equations_myfile within the folder of the XML file myfile.xml.

This editor does not pretend to be exhaustive. Complex equations can be created with another editor and added in Jaxe with a copy-paste.

Here are some rules to follow in order to make the best use of the editor :

  • Do not use spaces (they are ignored in the best case).
  • Write the equation as if it would be interpreted mathematically and a numerical result would be calculated. As a consequence, always specify the operators, even when they should not be displayed.
  • Use parenthesis to specify the order of the operations if it does not match the mathematical evaluation order.

As opposed to many equation editors, this editor analyses the mathematical meaning of the equation. It then builds the image from there. This makes it possible to get uniform graphical results for all equations. On the other hand, it is not possible to specify display constraints, for instance to obtain a little more space between two characters : the user gives the meaning for the equation, and the editor is in charge of finding the best display for it.
