Hexadecimal is a number system whoose base has 16 numbers. Hexadecimal is usually represented as 0 through 9 and A through F.
An example of counting from 9 to 33 follows.
9 A B C D E F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21
Hexa is a prefix derived from the Greek word for 6.
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.
latin
A shape with six sides is called a hexagon. You here is everywhere. In the latin term hexa- means six.
decimal
(159)decimal = (9F)HEX
It is C
That can't be an octal number; it has an 8 in it.
0xFFEF + 1 = 0xFFF0.
Hexa-decimal representation is given by, * 24 - 18 * 25 - 19 * 30 - 1E
Hexa is a prefix derived from the Greek word for 6.
Yes, hexa does mean 6. It is derived from the Greek word "hex" which means six.
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.
Hexa is a prefix meaning six. The most common words beginning with hexa have to do with 6-sided shapes. The polygon is a hexagon, and it can be described as hexagonal.
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.
