(** * Decimal or Hexadecimal numbers *)

Require Import Decimal Hexadecimal.

Variant uint := UIntDec (u:Decimal.uint) | UIntHex (u:Hexadecimal.uint).

Variant int := IntDec (i:Decimal.int) | IntHex (i:Hexadecimal.int).

Variant numeral := Dec (d:Decimal.decimal) | Hex (h:Hexadecimal.hexadecimal).

Scheme Equality for uint.
Scheme Equality for int.
Scheme Equality for numeral.

Register uint as num.num_uint.type.
Register int as num.num_int.type.
Register numeral as num.numeral.type.

(** Pseudo-conversion functions used when declaring
    Numeral Notations on [uint] and [int]. *)
