I was wondering if there was a method in ruby to obtain the hexadecimal
representation of numbers (ie. fixnum, floats, mainly) in either msb or in lsb
order.
Basically, I'm kind of looking for the opposite function of String#unpack().
I'm not 100% sure I understood the question, but does this do what you're after?
% ruby -e 'puts "%x" % 123'
7b
Hope that helps.

It's Array#pack.

Also there is to_s(radix):
128.to_s(16)
=> "80"
