Hex, decimal and binary conversion... make it simple

[hugoxp1]

Hi,


Maybe I will say something that for most of the users is "is already more than well known"... but for those like me... I'll post any way

When I was "googling" on the internet for a converter online from decimal to binary and to hex I've found that the only thing that we need is to use the windows calculator in scientific mode (win 7 is the "programing mode") and if we write a decimal value we only need to click in the radio buttons Hex, Bin... to convert that decimal value in Hex, Bin...etc and vice versa...

It's certainly well known to me, and I expect to a lot of others here as well. But it one of those things that is not intuitively obvious. One must dig to find it. Therefore, spreading the word on it is a good Idea. Thanks.

For those who find conversion between decimal, hexadecimal and binary, the table attached to post 20 here may be helpful.

If you look for the sequences and get familiar with doing the conversions mentally, it may become easier with time.

I use the calculator conversion quite a lot - though I would prefer it if leading zero padding for the binary and 4bit / 8bit spacing to make it easier to read were available as options. (You 'll see what I mean if you look at Westy's table. )

A couple of compilers I use have an optional always-on-top ASCII/Hex/Dec/Bin table which is handy too.

 

[westaust55]

If you want leading zeros shown, then one way is to do the calculation in Excel and set the cell format as "custom" and "0000"

Yuk,fire up Excel..? Should be an Editor/Compiler tool really.

Come on Westy write us a little executable/installable so we can have a floating conversion calculator

This is exactly why there is a Calculator shortcut on the View menu within Programming Editor....

Thanks Technical..... I for one, never did notice that before ...........

 

[John West]

I'd pulled that down and looked it over when I first installed the PE. I said "Hey, this is really well thought out." Then I immediately forgot about it. Sigh.

i found "borrowing" someones calculator and putting it in to binary mode is a great april fools joke, expecially if they have maths!

Yeah, the trick works well, as there are only 10 types of people in the world: Those who understand binary, and those who don't.

We have a poster of that in the IT rooms

i have a text file with all 8 bit bin hex and octal values and the ascii character and a short description

based on the terminal font this text file shows each character code as a text character
                        alt+      gives you
bin            hex    oct    dec    ASCII char    description or key
