Hi,
I was downloading the reference documentation in order to work on its translation to Portuguese, and some broken links  shown up. They are not that important, but in time, they could be corrected. Here they are:

1) In the file that describes arc() at
http://www.processing.org/reference/arc_.html
there is a broken link  named angleMode() pointing to
http://www.processing.org/reference/angleMode_.html
angleMode() has been removed in rev 69.

The text "These angles are specified in terms of radians by default, but by degrees if angleMode(DEGREES) has been called." could also be removed.

2) In the file that describes int
http://www.processing.org/reference/int.html
there is a reference to splitInts(). It is also gone after rev 69.

3) In the file that describe float
http://www.processing.org/reference/float.html
there is a reference to splitFloats(). It is also gone.

4) In the file
http://www.processing.org/reference/logicalNOT.html
the related link to &&(logical AND) shoul be changed from
http://www.processing.org/reference/.html
to
http://www.processing.org/reference/logicalAND.html

5) At the serial library pages, the link to last() is broken. It is missing and '_' character:
Change
http://www.processing.org/reference/libraries/serial/Serial_last.html
to
http://www.processing.org/reference/libraries/serial/Serial_last_.html

6) At the serial library pages, the link to lastChar() is broken. The file should be renamed. The link is correct.
Rename
Serial_lastchar_.html
to
Serial_lastChar_.html

That's it. As I said very small typos.
