What is 011111 01 as a number?

PlGLET
1.3975

(Original post by PlGLET)
[....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.

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
4. Thanks for that, I'll get on it! I'll +rep when I get on the main site! :-)

5. I went off & learnt that from the ocr site... & still got a different answer! :'D
