Trying to figure out what the inverse tangent function is...
(as in FORTRAN arctan)

Tried using:

$ result = atan2(u/v);
print "result = $result \n ";

Got error: "Too few arguments".

Any suggestions on either the function or where to look up math
functions for PERl?  Couldn't find it in "Programming PERL", by O'reilly.

Thanks in advance.
