Subject: how to tranlsate number to binary?

Hi, I am a ruby newbie. I want to write a program which will scan a
input file, change every digital number into  4 bits len's binary
number.
For example, for input.txt as

903
1047

I will get a new file as

100100000011
0001000001000111

Would anyboby kindly help to tell me how to do this?
