hi so u didn't understand that "why the last output number is 17?" well, how did u understand the other output numbers? they r in some "radix" right? first is binary, second is octal, third is decimal and forth is?? - Hexadecimal (base 16). base for, binary is -2 octal is -8 decimal is - 10 hexadecimal is - 16 so the 11 in, binary = 2*1 + 1 = 3 octal = 64*0 + 8*1 + 1 = 9 decimal = 10*1 + 1 = 11 hexadecimal = 16*1 +1 = 17 thats how we get 17. did i address ur problem? its just different radix systems... regards maulin
