NB: Functions with prototypes containing underscores in type names may be available only with certain extended compilers.
The value of the complex argument z (a two-element array with the real and imaginary parts in that order). is unrestricted.
For finite real-valued arguments, the real function range is [-1,+1].
The cx family of functions provide limited support for complex arithmetic when compiler or language support for a complex type is lacking.
