    double precision

    I'm asked to find the binary double precision IEEE floating point expression for a number.

    Do I just convert to binary like normal to answer this question?

    For example: If the number is 8...would my answer be 1000? Or do I need to do something else?

    Remember a floating point number is 52 bits long.

    I believe that 8_{10}=1000_2=1.0000000000000000000000000000000000  000000000000000000\times 2^{-3}

    If I'm mistaken, someone feel free to correct me.

    No, start by looking at the definition of IEEE types, see the Wikipedia article.
