Shell Programming and Scripting

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.

Code:

$ perl -e 'print sprintf("%b\n", 15);'
1111
$ perl -e 'print sprintf("%b\n", 18);'
10010

As for the list of functions, is this what you want (this is actually derived from perlfunc anyway)?

http://perldoc.perl.org/index-functions.html

As for variables, read perlvar:

http://perldoc.perl.org/perlvar.html

I was really wondering about finding the information in perldoc but those links will work great.
