    [....0.....0......0......0......0 ........0.....]
    [...-1...1/2...1/4...1/8...1/16...1/32...]

    Therefore;
    [...0...1...1...1...1...1...]
    As it goes down to 1/32, doesn't that mean I do;
    32/2 = 16
    32/4 = 8
    32/8 = 4
    32/16 = 2
    32/32 = 1 written like;

    (16+8+4+2+1) = 31
    32 32

    ? :-/

    Not too sure what the whole dividing by 2,4,16 and all that is...There are lots of methods to binary manipulation, you might have a different one.

    Like I say, the mantissa is dependent on your exponent, so you don't know what your place values for your mantissa is until you've calculated your exponent. It doesn't necessarily start with -1.

    Are there any books/websites etc that you'd recommend to learn this?

    Tbh, there's a lack of computer science resources so I kinda dug through the internet and picked up what I could.

    errr, I learnt best from http://www.ocrcomputing.org.uk/overview.html
    Go to F453 and the Data Representation section.
    Though its not very detailed it gives some examples. Aside from that I believe a site called CraignDave produce youtube videos. I haven't used them myself but they should have a tutorial on floating point binary. The key is to practice questions
