Deanery to Binary quick way

[brandonmufc06]

I remember doing a quick way of converting binary to deanery (I think) where it has something to do with halving the deanery number and ignoring the decimal place. (Or sommet along those lines) I know this is very vague but if anyone can tell me the method (Or any quick method) I would appreciate it. Thanks

Guessing you mean Denary and not Deanery

It only confused me because Deanery was the name of my high school, and i'd never heard it used for coding before

I learned to count on your fingers, it is actually quite easy and helps to learn binary. You can count upto 31 on a single hand!

 

A 1 represents a open finger, and a 0 represents a closed finger. I start with my lelft pinky finger for the left most digit, and work my way left.

1: 00001

2: 00010

3: 00011

4: 00100

5: 00101

6: 00110

7: 00111

 

 

 

The commonly taught way of converting from base 2 to base 10 is this method

 

16  8   4   2   1

 0   0   1   0   1

 

4 + 1 = 5

 

 

If you are adding two binary numbers, Its easier to keep them in binary.

 

 

1 0 1 0 0   +

 

0 0 1 1 1  =

 

1 1 0 1 1

 

 

 

To convert from Base 10 (Decimal) to Base 2 (Binary)

 

I would count up on my fingers for small numbers, but for big numbers the quickest why that I learned is outlined in this video: 

 

 

Okay, thanks
