Module `NumTok.Signed`Source

Sourcetype t = sign * Unsigned.t

Sourceval equal : t -> t -> bool

Sourceval is_zero : t -> bool

Sourceval of_nat : UnsignedNat.t -> t

Sourceval of_int : SignedNat.t -> t

Sourceval to_int : t -> SignedNat.t option

Sourceval is_int : t -> bool

Sourceval sprint : t -> string

Sourceval print : t -> Pp.t

sprint and print returns the number as it was parsed, for printing

Sourceval parse_string : string -> t option

Parse the string as a signed Coq number, if possible

Sourceval of_int_string : string -> t

Convert from a string in the syntax of OCaml's int/int64

Sourceval of_string : string -> t

Convert from a string in the syntax of OCaml's string_of_float

Sourceval to_string : t -> string

Returns a string in the syntax of OCaml's float_of_string

Sourceval of_bigint : num_class -> Z.t -> t

Sourceval to_bigint : t -> Z.t option

Convert from and to bigint when the denotation of a bigint
