Binary, Hex, and Octal

[David Wishart]

Forgive me if I've missed something in the documentation but are there any functions to convert between decimal/binary/hex/octal in Numbas?

I have a few questions that require these conversions,  is this a job for a custom function (I don't mind getting my hands dirty with some javascript if that is what is necessary)?

There weren't any functions to do that, but there definitely should be!

I've added new functions tobinary, tooctal, tohexadecimal and tobase to write numbers as strings in given bases, and functions frombinary, fromoctal, fromhexadecimal, frombase to parse strings representing numbers in those bases.

Thanks for the suggestion!

That was quick, thank-you.
