Types and arithmetic operations for complex arithmetic
are provided in Generic_Complex_Types, which is defined in
G.1.1.
Implementation-defined approximations to the complex analogs of the mathematical
functions known as the ``elementary functions'' are provided by the subprograms
in Generic_Complex_Elementary_Functions, which is defined in
G.1.2.
Both of these library units are generic children of the predefined package
Numerics (see
A.5). Nongeneric equivalents
of these generic packages for each of the predefined floating point types
are also provided as children of Numerics.
