NB: Functions with prototypes containing underscores in type names may be available only with certain extended compilers.
The value of the complex argument z is unrestricted.
For real-valued arguments in the range [-1,+1], the real function range is [pi,0].
When compiler support for complex types is lacking, consider using the cx family of functions instead.
