=head1 NAME

Perl::ToPerl6::Transformer::BasicTypes::Rationals::AddTrailingZero - Add trailing zero where needed


=head1 AFFILIATION

This Transformer is part of the core L<Perl::ToPerl6|Perl::ToPerl6>
distribution.


=head1 DESCRIPTION

Perl6 floating-point values have the format '1.0' where a trailing digit is required:

  1.0 --> 1.0
  1.  --> 1.0
  .1  --> .1

Transforms floating-point numbers outside of comments, heredocs, strings and POD.

=head1 CONFIGURATION

This Transformer is not configurable except for the standard options.
