Subject: Generate a hex string from integers

Hi there,

I'm new in Ruby. So, my question can seem simple for you. I need to 
generate a hex string from some digits: 1, 114, 3, 2 for example. I need 
the following hex representation: 00010072030002 - (0x0001, 0x0072, 
0x03, 0x0002).
I tried to use pack:

a = [1, 114, 3, 2]
hexStr = a.pack('iisi')

but it generate following string: 10007200302000

Also, what is the best way to convert this hex string into digits back?

Thanks in advance.

Michael
