>Thank you Hilmar, it helps. (espacially octal stuff)
You are welcome. You don't happen to need the opposite conversion (from decimal to other bases)?

>>2 should be multiplied by 8^2 (8 square; right now, I don't remember the syntax in Java). 2 should be multiplied by 8, and 4, simply by 1.

>>A shortcut, which sort of bypasses the use of powers, is:
>>
>>(2 * 8 + 3) * 8 + 4
>>
>>IOW: repeatedly multiply by 8, and add the next digit.

>>For hexadecimal, you would have to convert "A" to 10... "F" to 15, first, and then apply the same algorithm (multiplying by 16, of course).
