Perl conversion & perldoc question
Working my way through a perl book and can't find this;
You can convert from binary to ordinal numbers using 0b in front of the binary value but how do you go the other way, from ordinal to binary? Is there a function for this?
On Perldoc, is there a document that gives all of the available functions and system variables. I'm hunting for something other that Perlfunc, something that simply lists them all.

ppix::regexp::token::literal
PPIx::Regexp::Token::Literal(3pm) User Contributed Perl Documentation PPIx::Regexp::Token::Literal(3pm)
NAME
PPIx::Regexp::Token::Literal - Represent a literal character
SYNOPSIS
use PPIx::Regexp::Dumper;
PPIx::Regexp::Dumper->new( 'qr{foo}smx' )
->print();
INHERITANCE
"PPIx::Regexp::Token::Literal" is a PPIx::Regexp::Token.
"PPIx::Regexp::Token::Literal" has no descendants.
DESCRIPTION
This class represents a literal character, no matter how specified.
METHODS
This class provides the following public methods. Methods not documented here are private, and unsupported in the sense that the author
reserves the right to change or remove them without notice.
ordinal
print 'The ordinal of ', $token->content(),
' is ', $token->ordinal(), "
";
This method returns the ordinal of the literal if it can figure it out. It is analogous to the "ord" built-in.
It will not attempt to determine the ordinal of a unicode name ("N{...}") unless charnames has been loaded, and supports the vianame()
function. Instead, it will return "undef". Users of Perl 5.6.2 and older may be out of luck here.
Unicode code points (e.g. "N{U+abcd}") should work independently of charnames, and just return the value of "abcd".
It will never attempt to return the ordinal of an octet ("C{...}") because I don't understand the syntax.
SUPPORT
Support is by the author. Please file bug reports at <http://rt.cpan.org>, or in electronic mail to the author.
