Well, what I was trying to say is that number 2
by default in octave is float 2.0, so it represented
as 0000000000000040
If one wants integer 2, she has to use
int8(2) or similar.
"dec2hex" is another option:

octave:5> format native-hex
octave:6> 12
ans = 0000000000002840
octave:7> int8(12)
ans = 0c
octave:8> dec2hex (12)
ans = C

printf would work as well.
