unfortunately there’s no printf-style function in javascript.
look up “toFixed”, “toPrecision”, and “toExponential” on this page.
you have to convert the number to a string using these functions and
then add the resulting strings together with ‘+’.

if you really want something more like printf, you could try what this guy did:

note, i haven’t tested to see if toFixed etc. are working in Max/MSP
but I assume so.

Don’t know of any myself, but there is SO much info on the web.
(I rarely use print material these days..)
Just make sure you filter out the web-specific stuff, and find
references for the core language. Other than that, all you need to
know is in the Javascript for Max/MSP manual. (You might want to also
read an OpenGL manual if you’re interested in that.)

In fact that Mozilla page seems like a good starting place, in terms
of references:

http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Reference

(Not everything there will be applicable to Max of course..)

Personally I found this little guide quite useful too, though it
assumes a certain amount of knowledge in OO programming:

Hope this helps!
