Specifies the generic package of complex elementary functions known as GENERIC_COMPLEX_ELEMENTARY_FUNCTIONS. Does not supply the body of the package. Defines certain basic complex mathematical routines for building portable, reusable applications. Applies to programming environments complying with ISO/IEC 8652 and is relevant to the revised standard ISO/IEC 8652.
