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 C
(159)decimal = (9F)HEX
Hexa-decimal representation is given by, * 24 - 18 * 25 - 19 * 30 - 1E
0xFFEF + 1 = 0xFFF0.
That can't be an octal number; it has an 8 in it.
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.
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.
The hexadecimal system is a base 16 system, just as binary is base 2 and decimal is base 10. The same way that a binary system is more practical for hardware and software implications, hexadecimal is great for easy viewing of binary numbers. It's a lot easier, in the opinion of most, to look at 1FE4 than it is to get the same information as quickly from 0001111111100100. Hexadecimal numbers can also be easily converted to the seven segment display commonly used on electric signs and scoreboards to display numbers and some letters.
Hexa is a prefix derived from the Greek word for 6.
The Greek prefix for 6 is "hexa-".
The prefix for one sixth is "hexa-."
Yes, hexa does mean 6. It is derived from the Greek word "hex" which means six.
