21 The "PPI::Token::Number" class is used for tokens that represent
22 numbers, in the various types that Perl supports.
23
25 base
26 The "base" method is provided by all of the ::Number subclasses. This
27 is 10 for decimal, 16 for hexadecimal, 2 for binary, etc.
28
29 literal
30 Return the numeric value of this token.
31
33 Compared to Perl, the number tokenizer is too liberal about allowing
34 underscores anywhere. For example, the following is a syntax error in
35 Perl, but is allowed in PPI:
36
37 0_b10
38
40 - Treat v-strings as binary strings or barewords, not as "base-256"
41 numbers
42
43 - Break out decimal integers into their own subclass?
44
45 - Implement literal()
46
48 See the support section in the main module.
