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 real-valued arguments in the range [1, Infinity], the real function range is [+0, +Infinity], and Infinity is only possible if z is Infinity.
The cx family of functions provide limited support for complex arithmetic when compiler or language support for a complex type is lacking.
