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.
