Defines the specification of a generic package of elementary functions called Generic Elementary Functions and the specification of a package of related exceptions called Elementary Functions Exceptions. Specifies certain elementary mathematical functions which are needed to general floating point usage and to support generic packages for complex arithmetic and complex functions. Coverage includes: domain definitions, range definitions, infinities, underflow, and arguments outside the range of safe numbers.
