Syntax

2
formal_discrete_type_definition ::= (<>)
3
formal_signed_integer_type_definition ::= range <>
4
formal_modular_type_definition ::= mod <>
5
formal_floating_point_definition ::= digits <>
6
formal_ordinary_fixed_point_definition ::= delta <>
7
formal_decimal_fixed_point_definition ::= delta <> digits <>

Legality Rules

8
   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.
