### 1.4 Fixed-point Arithmetics and IEEE

So, we have seen how we can represent Binary positive and negative integers. Sadly, this does not help . You might have thought about an easy solution, just add a point somewhere. This is indeed correct and helps with this. So, how do you do it with binary numbers? Easy, the numbers to the right…

### 1.1 Addition and multiplication in binary and overflow?

Now that you know how to convert numbers in binary, you should also know a bit how to add numbers. We are focusing mainly on binary, because it is the most important for computer science. This method works mainly as with decimal systems. Let us see the basics: 0+0=0 0+1=1 1+0=1 1+1= 0 carry one…

### 1.0 Number Systems and converting between them.

In Technical Informatics, number systems are important. I mean, just like in any other field. You must know how to represent your numbers. A Number Representation is when you take a set of numbers and make it into a set and do operations with it. Sounds awfully like groups in abstract algebra (we talked about…
