Quaternary Base 4, Octal Base 8; Includes Tables
Numbering System to Decimal Base 10 Lessons
HAL says hi. 
Introduction and Start of Base Number Systems Tutorials
These four base numbering system lessons use the exact same teaching methodology. As such, when you have learned one, you will have learned them all. There is also some repetitiveness, purpose being to reduce unnecessary scrolling. Comparisons of different base number systems can also prove useful.If one understands the everyday, base 10 decimal number system; then you already understand the base 2, base 4, base 8, and base 16 numbering systems. You just don’t know that you know yet.
As you know, we use the decimal, base 10 numbering system in our daytoday lives. The decimal base 10 system has ten numbers (09) and orders of magnitude that are times ten. The lowestorder number represents itself times one. The nextorder number represents itself times ten. The next order number represents itself times 10 x 10 or itself times 100. The next order number represents itself times 10 x 10 x 10 or itself times 1000. And so on.
An example of the decimal base 10 system would be the number 7824. This number means there are:
 Four 1’s,
 two 10’s,
 eight 100’s,
 and seven 1000's.

Base 4, also known as the quaternary number system, is predominantly used in DNA genotyping and some electronics applications, etc. [A year 2019 update. Scientists have added four more letters to the DNA alphabet, so base 8 may also be relevant.]
This lesson gives you everything you need to know for converting from quaternary aka base 4 to decimal and for converting from decimal aka base 10 to quaternary. If you understand the decimal number system (or the binary base 2 numbering system for that matter), then you already understand the quaternary (base 4) number system.
Per the introduction, base 10 has ten numbers (09) and orders of magnitude that are times ten. The orders of magnitude are l, 10, 100 (10x10) , 1000 (10x10x10), etc.
An example would be the number 7112. This number means that there are:
 two 1’s,
 one 10’s,
 one 100’s
 and seven 1000’s.

How to Do Octal, Base 8 Number System Conversions. Includes Examples. 
Base 8, also known as the octal number system, is mostly used in electronics and some DNA applications, etc.
Here is everything you need to know on how to convert from octal aka base 8 to decimal. And for converting from decimal aka base 10 to octal.
As previously stated: if you understand the decimal (base 10) number system you use every day, then you already understand the octal (base 8) numbering system.
Per the introduction, base 10 has ten numbers (09) and orders of magnitude that are times ten. The orders of magnitude are l, 10, 100 (10x10) , 1000 (10x10x10), etc.
An example would be the number 2375. This number means that there are:
 five 1’s,
 seven 10’s,
 three 100’s
 and two 1000’s.
How to Do the Octal Base 8 Numbering System
Electonics and Base 8 Octal 
Base 8 uses the same base 10 structure, the only difference being the orders of magnitude.
Base 8 has eight numbers (07) and orders of magnitude that are times
eight. The lowestorder number represents itself times one. The
nextorder number represents itself times eight. The next order number represents itself times 8x8 or itself times 64. The next order number represents itself times 8x8x8 or itself times 512. And so on.
A basic, first example of an octal number would be the base 8 number 11111. This would mean there is:
Another base 8 example would be the octal number 321. This number means that there are:
Another base 8 example would be the octal number 4075. This number means that there are:
Hexadecimal (base 16) is the primary base numbering system used by computer programmers. Hex code is used in everything from core dumps to color codes and everything inbetween.

Nice read, I just passed this onto a friend who was doing a little research on that.
ReplyDeleteAnd he actually bought me lunch since I found it for him
smile So let me rephrase that: Thanks for lunch!
