Converting to hex (Newbie) 1

[digitalwm]

I have a question. How can i convert a number from decimal to hex in ruby, only with rubby built in functions? An example will be apreciated, or even a link to some documentation. I have read the Official Manual, many many times, i haven't found nothing to meet my request. I used even ".pack" and ".unpack" but they don't work.

EX:
i have a number "nr=37"
how do i find oout the value in hexa on nr?

Thank You

You have to convert items using methods such as String#to_i(base=10)and Fixnum#to_s(base=10). These would be for decimal values. Change to (base=16) for hexadecimal values, (base=2) for binary values, etc.

For getting answers on Ruby I highly suggest the Ruby IRC channel #ruby-lang on irc://irc.freenode.net as well as checking out the Ruby mailing list archives at

http://blade.nagaokaut.ac.jp/ruby/.

That's where I go since the Ruby Forum has been down for awhile now at

http://www.ruby-forum.org/bb.

Hope this helps. Enjoy Ruby!!
