    Bit problem

    We are working on determining the number of bits required to represent different decimal numbers. I was doing fine until I hit

    3^1000 Can anyone help me out???? I think I am missing something really basic but alas I know not what!!!!

    The number of bits needed to represent an integer N is \lfloor \log_2(N)\rfloor +1 and \log_2(3^{1000})=1000\log_2(3)=1584.96..
