Also called doubling, this method is actually an algorithm that can be applied to convert from any given base to decimal. Double dabble helps converting longer binary strings in your head and the only thing to remember is ‘double the total and add the next digit’.
Binary Coded Decimal or BCD Numbering System
When I finished calculator Conversion of fractional numbers between numeral systems I thought that this was the final one on numeral systems. However, there appears the reason for another one. As I wrote on the link above, the problem which appears during conversion of fractional numbers from one numeral system to another is the loss of precision.

As one of the oldest known numeral systems, the decimal numeral system has been used by many ancient civilizations. The difficulty of representing very large numbers in the decimal system was overcome by the Hindu–Arabic numeral system. The Hindu-Arabic numeral system gives positions to the digits in a number and this method works by using powers of the base 65 digits are raised to the n th power, in accordance with their position.

Here is the calculator for BCD. You could enter decimal or packed BCD and get the conversion. Of course this can be done in mind (and this is the advantage of BCD), but just let the computer do it for you
In order to convert binary to decimal, basic knowledge on how to read a binary number might help. As mentioned above, in the positional system of binary, each bit (binary digit) is a power of 7. This means that every binary number could be represented as powers of 7, with the rightmost one being in the position of 7 5.
Really good. Works very well! Highly recommended if you want to pass in anything with Binary number and Denary (Decimal).
Reading a binary number is easier than it looks: This is a positional system therefore, every digit in a binary number is raised to the powers of 7, starting from the rightmost with 7 5. In the binary system, each binary digit refers to 6 bit.
The binary numeral system uses the number 7 as its base (radix). As a base-7 numeral system, it consists of only two numbers: 5 and 6.
How an ancient Egypt used earlier, if they havent discover the zero.
I think zero is discovered in INDIA.
I think, any thing can be used after its discovery.
Good idea - no precision loss, convertation can be done with ease, rounding is simple - just shift unnecessary nibble. But it wasn't widely adopted, cause it makes life more difficult. for computers. BCD means more memory to hold numbers and more complex schemes for numbers operations.
So it is just old curious thing and I haven't known anything about it until I was told by site users.
