NAME

       PPI::Token::Number - Token class for a number

SYNOPSIS

	 $n = 1234;	  # decimal integer
	 $n = 0b1110011;  # binary integer
	 $n = 01234;	  # octal integer
	 $n = 0x1234;	  # hexadecimal integer
	 $n = 12.34e-56;  # exponential notation ( currently not working )

INHERITANCE

	 PPI::Token::Number
	 isa PPI::Token
	     isa PPI::Element

DESCRIPTION

       The "PPI::Token::Number" class is used for tokens that represent numbers, in the various types that Perl supports.

METHODS

   base
       The "base" method is provided by all of the ::Number subclasses.  This is 10 for decimal, 16 for hexadecimal, 2 for binary, etc.

   literal
       Return the numeric value of this token.

CAVEATS

       Compared to Perl, the number tokenizer is too liberal about allowing underscores anywhere.  For example, the following is a syntax error in
       Perl, but is allowed in PPI:

	  0_b10

TO DO

       - Treat v-strings as binary strings or barewords, not as "base-256"
	 numbers

       - Break out decimal integers into their own subclass?

       - Implement literal()

SUPPORT

       See the support section in the main module.
