sorry to be blunt but this is math, and thus pretty rigid as to which one is the correct result.
You can check WolframAlpha if that adds more weight to the "credibility of options":

Logan is correct, the "glitch" occurs in the ATAN function.

All my sources have been saying that 1+i*0 = 1*e^(0*i) = +1 ... in this case 1*e^0 , As given z=a+i*b=ABS(z)(cos(w)+sin(w)*i=ABS(z)*e^(i*w))
So the calculation should behave excactly like with integer 1. (with this knowledge of mine)

Is the problem with intel decimal library? Isn't the newRPL using it also or do I remember incorrectly?
