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.
Hexa-decimal representation is given by, * 24 - 18 * 25 - 19 * 30 - 1E
It is called 'Icosi-kai-hexa-gon'. (Icosi means 20, Kai means and, hexa means six and gon is the final suffix)
Most polygons have numerical prefices which are derived from Greek. The exception are quadrilateral and nonagon which use Latin prefices. The Greek prefix for six is hexa.
12. (deca = 10, octo = 8, hexa = 6 etc)
It is C
hexa decimal system is used in computer system because computer is especially formed for the calculation. Hexa decimal is a collection of number 0-9 and A-F where a large numbers are include so from this we can easily calculate the large numbers.
That can't be an octal number; it has an 8 in it.
0xFFEF + 1 = 0xFFF0.
6 and 8, but: Hexa as in Hexa-Decimal mean 16 number system. ie: 0123456789ABCDEF : 16 digits. 10 decimal + 6 hexa. Octa as in a numbersystem mean 8 number system. ie: 01234567 : 8 digits. A Hexagon is a polygon with 6 sides. An Octagon has got 8 sides. Examples of numbers in these number systems: 10, 12, 14 =Decimal A, C, E = HexaDecimal 12, 14, 16 = OctaDecimal All representing the same number just in different systems. Additional information: We use the Decimal number system because it is by far the easiest to do calculations with. It has become a world wide standard. We use HexaDecimal and Binary in computers. Octa as in a number system has got no widespread uses as to my knowledge. It might be used in various coding schemes to make information less obviously visible.
(159)decimal = (9F)HEX
If you continue adding one more, the next number is F10. (F means 15, and that is the largest number that fits into a single digit.)
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.
24.6391 is represented in IEEE real*4 (32-bit real number) as: 0x41c51ce0 (big-endian) 0xe01cc541 (little-endian)
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.
