[edit] Parameters
| z | - | complex argument | 
[edit] Return value
The complex arc cosine of z in the interval [0; π] along the real axis and in the interval (−∞; ∞) along the imaginary axis.
[edit] Example
Run this code
Output:
ccos(1.0+2.0i) ==> 2.032723-3.051898i cacos(2.032723-3.051898i) ==> 1.000000+2.000000i
