Realcomplex

Realcomplex is not a standard mathematical term with a single, universally accepted definition. In technical writing it may be used informally to refer to objects or systems that involve both real-valued and complex-valued data, or to tools that support computations with real and complex numbers. Because of its generic nature, the meaning of realcomplex varies by context.

In mathematics, the real numbers R and the complex numbers C are distinct fields. Some authors may use "realcomplex" to describe constructs that simultaneously handle real and imaginary components—such as a complex-valued function defined on a real domain, or a representation that stores a real part and an imaginary part. However, this usage is nonstandard and should be clarified in the given work.

In computing and software, "realcomplex" may appear as a project or product name, or as a namespace associated with numeric types. Without a specific reference, it is not possible to attribute a fixed feature set or API to the term. Users encountering the term should consult the corresponding documentation to determine its scope and semantics.
