f.each_byte {|x| print x.to_s(base=2).rjust(8,'0')
the above will fail in 1.6.4
wanna ask if to_s(base=2) is only available in 1.8?
my intention is to get each byte and output it as 10101010 format. Is
there any way that i can do that in 1.6.4?
thank you.
I cannot test with 1.6.4 but probably the following works
"%b" % x
Pas d'quoi

Can't speak to the Ruby 1.6 issue, but the base= doesn't add anything to
your code (it just assigned 2 to a local variable). Just call x.to_s(2)
