3.3.2 Number Declarations
A number_declaration declares a named number.
number_declaration ::= defining_identifier_list : constant := static_expression;
Name Resolution Rules
The static_expression given for a number_declaration is expected to be of any numeric type.
The static_expression given for a number declaration shall be a static expression, as defined by clause 4.9.
The named number denotes a value of type universal_integer if the type of the static_expression is an integer type. The named number denotes a value of type universal_real if the type of the static_expression is a real type.
The value denoted by the named number is the value of the static_expression, converted to the corresponding universal type.
The elaboration of a number_declaration has no effect.
Examples of number declarations:
Two_Pi : constant := 2.0*Ada.Numerics.Pi; -- a real number (see A.5)
Max : constant := 500; -- an integer number Max_Line_Size : constant := Max/6 -- the integer 83 Power_16 : constant := 2**16; -- the integer 65_536 One, Un, Eins : constant := 1; -- three different names for 1
