#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.
