[edit] Parameters
| z | - | complex argument | 
[edit] Return value
The complex arc tangent of z in the interval (−∞; ∞) along the imaginary axis and in the interval [−π/2; +π/2] along the real axis.
[edit] Example
Run this code
Output:
ctan(1.0+2.0i) ==> 0.033813+1.014794i catan(0.033813+1.014794i) ==> 1.000004+1.999996i
