=head1 NAME
PPI::Token::Number::Float - Token class for a floating-point number
=head1 SYNOPSIS
$n = 1.234;
=head1 INHERITANCE
PPI::Token::Number::Float
isa PPI::Token::Number
isa PPI::Token
isa PPI::Element
=head1 DESCRIPTION
The C<PPI::Token::Number::Float> class is used for tokens that
represent floating point numbers. A float is identified by n decimal
point. Exponential notation (the C<e> or C<E>) is handled by the
PPI::Token::Number::Exp class.
=head1 METHODS
=cut
use strict;
use PPI::Token::Number ();
use vars qw{$VERSION @ISA};
BEGIN {
$VERSION = '1.236';
@ISA = 'PPI::Token::Number';
}
=pod
=head2 base
Returns the base for the number: 10.
=cut
sub base() { 10 }
=pod
=head2 literal
Return the numeric value of this token.

my $neg = $str =~ s/^\-//;
$str =~ s/^\./0./;
my $val = 0+$str;
