Re: mathfun

Hi Hans,

Thanks for the new features you have introduced in the module mathfun.
Actually I have been using commands such as the one mentioned by Aditya,
	\ctxlua{myfunction(args)}
but for the formatting of the output, that is when one wants only 3 or four decimal digits, that approach is not very handy.
So I will use the new feature and I’ll put it on the wiki once I have a few interesting examples.
By the way, what does 

	\complexexpr{123 + new(456,789)}

mean?

Best regards: Otared
