Re: atan2 template

Cool, yes -- if one can live with the limited precision.

When offered on a piece by piece basis such algorithms and implementations are just a little bit more than curiosity.

What I really wanted to emphasize was that FXSL provides *complete set of functions* -- be it trigonometric, hyperbolic-trigonometric, exponental, logarithmic, ... etc,  and their reverse functions.


Add to this the findRoot template, which implements Newton/Raphson and binary-search algorithms for finding the root of any 1-argument fuction over R  -- and you have a most powerful toolset implemented in XSLT and ready to use since 2002.

Do note, that one can specify the desired precision as a parameter to any of these functions.

But it's such a *cool* wheel.....
