Matrix operations in particular can quickly accumulate rounding errors.

Someone with experience in this kind of thing could look at the routines in runtime/scripts/math.js and improve them.

Numbas began before there were any good libraries of maths functions in JavaScript, but now there are quite a few. What would it take to replace our versions of common maths functions with an imported library?
