[fpc-pascal]Error on arctan2 documentation

[Manuel Ritto Correa]

On FreePascal the following insctruction:

  Writeln(arctan(2),arctan2(2,1),arctan2(1,2));

Yields:

 1.1071487177940905E+0000 1.1071487177940905E+0000
4.6364760900080612E-0001

I believe this is in contradiction with the docomentation where it is
said that

arctan2(x,y) calculates atan(y/x)

It would be OK if the documentation stated

arctan2(y,x) calculates atan(y/x)
        ^^^
Since I am not receiving any messages from the FPC mailing list, and I
know that some developpers of FPC read this newsgroup, I am posting it
here.

By the way: I find Free Pascal great!!

P.S. I've posted this earlier to comp.lang.pascal.misc, because I was
having problems with this mailing list. But this is the right place to
post, so, there you have it!
