PPI::Token::Number isa PPI::Token isa PPI::Element
DESCRIPTIONThe "PPI::Token::Number" class is used for tokens that represent numbers, in the various types that Perl supports.
baseThe "base" method is provided by all of the ::Number subclasses. This is 10 for decimal, 16 for hexadecimal, 2 for binary, etc.
literalReturn the numeric value of this token.
CAVEATSCompared 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:
TO DO- Treat v-strings as binary strings or barewords, not as ``base-256''
- Break out decimal integers into their own subclass?
- Implement literal()
