Module `NumTok.Unsigned`Source

Sourcetype t

Sourceval equal : t -> t -> bool

Sourceval is_nat : t -> bool

Sourceval to_nat : t -> string option

Sourceval sprint : t -> string

Sourceval print : t -> Pp.t

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

Sourceval parse : char Stream.t -> t

Parse a positive Coq number. Precondition: the first char on the stream is already known to be a digit ([0-9]). Precondition: at least two extra chars after the number to parse.

The recognized syntax is:

integer part: [0-9][0-9_]*
fractional part: empty or .[0-9_]+
exponent part: empty or [eE][+-]?[0-9][0-9_]* or
integer part: 0[xX][0-9a-fA-F][0-9a-fA-F_]*
fractional part: empty or .[0-9a-fA-F_]+
exponent part: empty or [pP][+-]?[0-9][0-9_]*

Sourceval parse_string : string -> t option

Parse the string as a non negative Coq number, if possible

Sourceval classify : t -> num_class
