Summary 0002513: arcTan: returns angle in strange intervale
Description arcTan: returns angle in the intervale [-pi/2 ; 3pi/2] instead of the more conventional [-pi ; pi]

For example:
(1 / 2 sqrt) arcTan: -1/ 2 sqrt
returns 3.92699081698724
instead of 2.356194490192345

Included a fixed version of the arcTan: method.
Please include it, I need it!

arctan: has no senders in the current image and Hilaire is the math teacher here... ;-)

So I would vote for adding it to 3.9a
