F.1 Machine_Radix Attribute Definition Clause

Static Semantics

Machine_Radix may be specified for a decimal first subtype (see 3.5.9) via an attribute_definition_clause; the expression of such a clause shall be static, and its value shall be 2 or 10. A value of 2 implies a binary base range; a value of 10 implies a decimal base range.

Implementation Advice

Packed decimal should be used as the internal representation for objects of subtype S when S'Machine_Radix = 10.

Examples

Example of Machine_Radix attribute definition clause:

type Money is delta 0.01 digits 15;
for Money'Machine_Radix use 10;
