Happy to lose the contest as it looks like we will all win in the end thanks to Franck's sharp eye!
I used arguments from .1 to 1.1 step .1 when testing and was working with degrees as output so atan(1) = 45. The consistency of atan vs. atand needs 'attending' to.
btw I extended the series out a bit in mp-tool and it did not converge quickly.
Also interesting that we are using calculators to test ;-) Thanks all!
