I will try and explain the basics it is a number that is split into 3 sections.

That would be 5.75

Can you see how that works. All is added up in the normal way. Add up the 2 part seperatly.

so if you use the same structure above you can work out the following

01100110
that means positive number as no sign bit.
Then working from left we have 4+2 . (.25) + (.125)
So that would be 6.375

Just remeber the binary always goes ether side of the floating point. Numbers are read from the floating point out. That means before the decimal point each value will double the future you are away from the decimal place. And if you are going right of the point it will go 1/n were n will double the further away from the point you go.

I hope that makes sense. It is very hard to explain.

Could you get my e-mail of my profile and add me to messenger please.

I am on a Course all of this week so I will not be able to say I will be able to look at them straight away but if you send me the examples then I have no problem with helping you through some of the scenarios.
