Each hexadecimal digit converts to a 4-digit binary string as follows:0 = 0000, 1 = 0001, 2 = 0010, 3 = 0011,
4 = 0100, 5 = 0101, 6 = 0110, 7 = 0111,
8 = 1000, 9 = 1001, A = 1010, B = 1011,
C = 1100, D = 1101, E = 1110 and F = 1111.
So, for example D3A (hex) = 110100111010 (Binary)
It is 1010101111001101.
You don't use binary because it's very hard reading a bunch of zeros and ones. You use hexa because each hexa digit corresponds to 4 bits, this makes it very easy to convert from hexa do binary and vice versa. For a similar reason you use octal because each digit corresponds to 3 binary digits. Example: 0101 10102 Has 8 binary digits so it will be 2 hexa digits: 01012 = 516 , 10102 = A16 So the full number will be: 0101 10102 = 5A16 This works for hexa and octal because 16 and 8 are powers of 2, it would also work for 4, 32, 64 or any other ower of 2 . Since 10 for decimal notation is not a power of 2 converting from binary is not so direct.
The binary equivalent would be... 1010101101011101 - There is a multi-functional calculator built-in to Windows which can covert numbers between Hex, Decimal, Octal and Binary.
Computers do much of their processing in binary. Hexadecimal is used as a kind of shortcut (easier to read for humans): each hexadecimal digit represents four binary digits.
The number 47 in binary would be 101111
489 = 111101001
It is C
13541
110101001 = 651 octal
In theory, yes.In practice, you would have to change the mechanism from its decimal design to the octal or binary design.
The number of atoms of each element in a binary molecular compound is indicated by numerical prefixes. These prefixes precede the name of each element in the compound, indicating the number of atoms present.
That can't be an octal number; it has an 8 in it.
