Number Representations in Computer Hardware, Explained

[ma3mool]

Welcome to a most fundamental area of computer design: how numbers are represented in hardware! We know that modern computers use and are very efficient at using binary, but wasn't always the case.

Thank you for this wonderful article...

We use to play number games in College... and leave binary messages on door boards..!

I'm not good enough at math to understand much but it was a very interesting read.

Excellent article.

This is the kind of article that got me on TS in the first place. Shame they turned out to only make up like 1 out of every 40 or 50, but I'm nevertheless grateful for this quality content.

I had to read through this article twice to make sure I was retaining the information correctly lmao

Great article, thx a lot !

A very interesting article. Although for me it didn't really explain the need for the bias in the exponent field of floating point representations.

Excellent question. The short answer is that the bias allows you to get both positive and negative exponent values. So, if you want to get 2^-3, the bias allows you to encode it in a very straightforward way, by using the 8-bits for 124.

The longer answer is that it has to do with 2's complements, which isn't discussed here at all. It turns out that using a bias just makes life easier for the hardware, then having to interpret a 2's complement number and figure out if it is positive or negative.

Good read, thanks.

One thing: it's a fundamental tenet, not tenant

Good read, thanks.

That's right 'coz 'a fundamental tenant' is one whose dogma pisses all over your karma...

F**k me if I or most of us will really, truly understand the math that cpu is doing. I think the majority comes here for tech news and review discussion.
