12.5.2 Formal Scalar Types

A formal scalar type is one defined by any of the formal_type_definitions in this subclause. The class determined for a formal scalar type is discrete, signed integer, modular, floating point, ordinary fixed point, or decimal.

Syntax

   
       formal_discrete_type_definition ::= (<>)

       formal_signed_integer_type_definition ::= range <>

       formal_modular_type_definition ::= mod <>

       formal_floating_point_definition ::= digits <>

       formal_ordinary_fixed_point_definition ::= delta <>

       formal_decimal_fixed_point_definition ::= delta <> digits <>

Legality Rules

The actual type for a formal scalar type shall not be a nonstandard numeric type.

NOTES

(12) The actual type shall be in the class of types implied by the syntactic category of the formal type definition (see 12.5, ``Formal Types''). For example, the actual for a formal_modular_type_definition shall be a modular type.
