    Ugh. I know how to do this but it will take me ages.

    Is that one number, or are they to be added up?

    It looks to be 80 characters and so is a number between 1 and 2^(80). If it is one binary number that is.

    The principle of binary representation and translation from binary to decimal are straightforward. That assumes binary. It could be in any base to begin with. It could be in base 10 already and the task is to convert TO binary. After all, 1001 is a number in base 2, 3, 4, etc.

    I don't see why it begins with a zero. If it is one binary number, there is no need to state a leading zero unless it is the readout of an 80 digit register. If it is two numbers, the same question applies.

    So you have a procedure in mind? Expressing such large numbers (powers of 2) and adding them could be tedious.

    I assume if it wa a very large number represented in binary it would be all on one line.
    Therefor, i'm thinking the idea is to take the bottom line from the top first?

    hmm.

    C,0D9,DEC,A94 if added together,
    2,40F,E90,12E if subtracted.

    Hex seems suitable for brevity.

    Looks like ASCII to me. I don't have time to translate it right now if it is, though.

    Every four binary digits corresponds to one hexadecimal digit (0000=0 up to 1111=F), so usually binary numbers are written in groups of four.

    0100111001100101011100100110010001110011
    is better written as
    0100 1110 0110 0101 0111 0010 0110 0100 0111 0011,
    which quickly translates as
    4,D65,726,473,
    or about 3.32414 x 10^11.

    Who writes hex numbers with a comma every three digits?!
