Binary to BCD Converter (double dabble machine) tutorial 1.16.4 +

The application of BCD is useful when wanting to make binary numbers display in decimal. There are other applications, but displays is a common use in Minecraft computational red stone. Btw only stacks to 16 bits worth of decimals places my bad XD

Hey so um for some reason the machine is allowing things like 1111 or 1100 or 1010 in which shouldn’t be a thing please help

WHY DONT ANYONE HAVE A 16 BIT ONE
(sorry for caps don't want to ride it again)

This might be kind of slow but atleast its faster than 1000 block long decoders

You've earned my sub, man! Exactly what I needed

Save for survival, wish me luck, Great Video Thanks!!!! Grettings

This would have helped so much a year ago when I started lmao, I could only figure out how to display in Hex, never Decimal, thanks!

I got it working. However say the first 2 input are That will have to be to shift it an extra 2 times(total 10 times) to get correct answer?. For however many 0s you have will have to shift extra

But if the 1st line is on. Then no problem. Help

this was really useful, i was wondering how you could then take the outputs from each decimal place and put them into a display, maybe a 7 seg display? cheers!

It's working on Bedrock Édition ?

Oh my goodness this was so helpful. So I've been working on my first attempt at a calculator and needed an efficient way of displaying the output and wanted to do some research and I discovered the double dabble algorithm but couldn't figure out how to implement it. (I'm still new to this). Essentially, this helped a lot and once I had this I could run the output into a Seven Segment Display with ease. Much appreciated my guy.

Very amazing video it helped me a lot when building a 8bt calculator in my project.
Thanks for a very good video.

I've rebuilt this (with 4 digit output and 12 bit input) and it works fine for some numbers but strangely for others it doesn't work. Most of the cases it's off by some multiple of 6 and/or 10. Example: Input: 2048&512 --> Output: 2 thousands, 5 hundreds instead of 2 thousands, 5 hundreds, 6 tens
Input: 64&32 --> Output: 9 tens instead of 9 tens, 6 ones
But when the input is for example 16&32&64&128 the output is correct (240)
Please HELP!

Uhhhh anyone can offer help? When I go to do the shifting to test 30, it moves by many blocks at a time, and by the 4th or 5th press, it is already out of the registers. I am on bedrock if this helps.

Edit, it seems the piston that is fed by his test button does not actually get powered. This is a slight issue.

THANK YOU SO MUCH. You’re tutorials are easy to follow and to the point, and it’s just place this so we don’t get confused by logic. This works so well for what I need to do and I may continue to use this design for a long time. THANK YOU SO MUCH.
