Decimal System.
The decimal numeral system is the most commonly used and the standard system in daily life. It uses the number 10 as its base (radix). Therefore, it has 10 symbols: The numbers from 0 to 9; namely 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
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 10; digits are raised to the n th power, in accordance with their position.
For instance, take the number 2345.67 in the decimal system:
The digit 5 is in the position of ones (10 0 , which equals 1), 4 is in the position of tens (10 1 ) 3 is in the position of hundreds (10 2 ) 2 is in the position of thousands (10 3 ) Meanwhile, the digit 6 after the decimal point is in the tenths (1/10, which is 10 -1 ) and 7 is in the hundredths (1/100, which is 10 -2 ) position Thus, the number 2345.67 can also be represented as follows: (2 * 10 3 ) + (3 * 10 2 ) + (4 * 10 1 ) + (5 * 10 0 ) + (6 * 10 -1 ) + (7 * 10 -2 )
Binary System.
The binary numeral system uses the number 2 as its base (radix). As a base-2 numeral system, it consists of only two numbers: 0 and 1.
While it has been applied in ancient Egypt, China and India for different purposes, the binary system has become the language of electronics and computers in the modern world. This is the most efficient system to detect an electric signal’s off (0) and on (1) state. It is also the basis for binary code that is used to compose data in computer-based machines. Even the digital text that you are reading right now consists of binary numbers.
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 2, starting from the rightmost with 2 0 . In the binary system, each binary digit refers to 1 bit.

Please Explain How Negative number Stored In Binary and Conversion of the Same.
This really helped me. I love computers. Yay software.
Write out the table of 2's - 1 2 4 8 16 32 64 128 256 0 1 0 1 0 1 0 0 0 say you want to know what 42 is in binary start at the table from right to left, so start with 256 column, if 256 is > than 42 then put a 0 in the 256 column, 128 is > 42 so a zero in the 128 column, 64 is > 42 then another zero, 32 10 so put a 0 in the 16 column, then next number in the row is 8 and 8 can be subtracted from 10 so put a 1 in the 8 column, 10 - 8 leaves 2 left, 4 is > than the remaining 2 left so put a zero in the 4 column, the next number in the row is 2, so 2 - 2 = 0 so put a 1 in the 2 column, since there's nothing left put a 0 in the 1 column. now looking at your chart you can read your binary number from right to left, which is 010101000 which = 42 in binary options.
Now I can cheat in my computer exam . Thanks .
Very nice apk make my work easy.
Things made really easy .
Really helped for a baddie like meh, now I can pass my computer exam.
Quick, Easy and Simple.
How to convert fractional decimals to binaries?
Helped me cheat in my electrical electronics test.
@madan I have always had a problem with Binary. I found it easiest to remember the power of 2 up to a certain number (usually 128 is something I start with), and then you can extrapolate up from there. So what I do to do this freehand, I start with a number I know, let's say you remember 64 is the highest 2 bit operator you remember, so I multiply that until I get over the number I have to convert. So 1024 is too large, so 512 is the first binary number that isn't too large, so you set the bit to 1. 1 Next is 256, and the remainder from subtracting 512 from 789 is 277. You set the bit to 1 to indicate 256. 11 Next is 128, but your remainder is 21. That bit is 0. 110 64, More inspiring ideas bit is 0. 1100 32, your remainder is 21, so the bit is 0. 11000 16, which is less than 21. So the bit is 1. Remainder is now 5. 110001 8 is the next 2 bit, it's greater than 5 so the bit is 0. 1100010 4, remainder 1. Bit is 1 11000101 2, bit is 0 110001010 1, bit is 1 1100010101 It's tedious, but works. I checked against the calculation on the page, and it's accurate. If you need to put it in bytes, it would be 0011 0001 0101. Each byte is 4 bits, zero padded.
