Here'e an example of how to register a nick on Freenode IRC. It's a little tricky, but if you follow some simple steps, you'll get through it okay. All you need to do is connect to the Freenode IRC network and have a little talk with NickServ.

The first and most confusing questions can be combined:

1. How do I know if my nick is already registered to someone else?
2. How do I talk to NickServ?

Start by connecting your client to irc.freenode.net and joining any chat.

//For those of you that don't get it this technique is called scaling. Basically what the answer does here is bring two figures across the decimal point turning the figure into a whole number to avoid all the crazy floating point issues, round that and then translate it back into what it was before by dividing by 100 and you have your answer to 2dp.

Math.round((num + 0.00001) * 100) / 100
