When disregarding the 'isnan()', the function is returning a '2' when

If you ask me, it should exit on the first compare and thus return a
not-a-number.
You cannot "exit" a comparison in C, one of the branches is always taken,
which means that npx_dr11_inverse_tangent_series can never return -NAN.
Well, I have an Intel manual here that states that any operation on a
QNaN should return a QNaN, which means that also the compare should
return a QNaN when one or both of the arguments is a QNaN.
