How to report bugs and make suggestions is described on the community page.

Version 4.3


  • 1st version of API.
  • Better install code (see #332).
  • Better CSS, including "tool tips". May need to refactor JavaScript. (See issue #380)
  • A STACK Maxima function which returns the number of decimal places/significant figures in a variable (useful when providing feedback). Needed for the refactoring.
  • Enable individual questions to load Maxima libraries. (See issue #305)
  • Re-sizable matrix input. See Aalto/NUMBAS examples here, with Javascript.
  • Add support for matrices with floating point entries, and testing numerical accuracy.
  • Update MCQ to accept units.
  • Add a base N check to the numeric input.
  • Expand support for input validation options to matrices (e.g. floatnum, rationalize etc.)
  • Add in full parser, to address issue #324.
