This new version becomes a primitive operation of the new type and are themselves inherited by any further derived type.
Each Tagged type has an associated type denoted by T'Class which comprises the union of all the types in the tree of derived types rooted at T.
If the names and types of these new components are to be kept "private" to the package in which the derived type is defined, a private extension part may be specified:
Because of Ada 83's preexisting support for derived types, this modest generalization is adequate to provide full support for what is called "single inheritance" .
Defence has a large number of containers in accordance with ISO 1C and 1CC and derived types
Brent's MP package [Brent 1978] did not support complex arithmetic, and Bailey's more recent MP package [Bailey 1993; 1995] provides complex arithmetic and some complex elementary functions and contains a Fortran 90 module defining multiple-precision derived types.
Table I lists the operations defined in the interface module for the three derived types.
Available Operations for Multiple Precision Derived Types = real integer complex HUGE + real integer complex INT - real integer complex LOG * real integer complex LOG10 / real integer complex MATMUL ** real integer complex MAX .
