Hello,

I think I understand hexadecimal i.e.

3B0E8 = 3x10^4 + 11x10^3 + 0x10^2 + 15x10^1 + 8x10^0 = 41,158

but is there a difference between:

•unicode & hexidecimal unicode?
•hexidecimal & hexidecimal unicode?

Thanks

Hexidecimal and unicode have nothing to do with each other except that Unicode sometimes uses a hexidecimal representation for some characters where the binary codes can't be used.

Hexidecimal is a character representation of binary values using the characters 0-9 and A-F.  http://en.wikipedia.org/wiki/Hexadecimal  Note that many computer languages use some kind of prefix to tell the interpreter or compiler that a hexidecimal number follows.

Unicode is a system to represent characters in almost all languages.

I think I understand hexadecimal...

Please note that hex 3B0E8 = dec 241896, not 41,158.

Hexadecimal is a number base, base 16. Unicode is a character encoding scheme. Technically, they are two different kinds of things.

They are two different things and they are completely different.
Hexadecimal is a base 16 notational number for representing real numbers. For more details please see the following:-
http://mathworld.wolfram.com/Hexadecimal.html

Whereas Unicode is a character set, which represents texts in various writing scripts. See the following:
http://en.wikipedia.org/wiki/Unicode

Since the number base of hexadecimal is 16, your calculation require replacement of 10 with 16. 10 is for decimals, 2 for binary and 8 for octal.

I just noticed that you got the Hex calculation wrong.  It all should be base-2.

3B0E8 = 3x2^16 + 11x2^12 + 0x2^8 + 15x2^4 + 8x2^0 =  241896 decimal
