RE: Subtracting Hexidecimal Salem (Programmer) 25 Sep 08 14:49 They're the same as for subtracting numbers in any other base. -- If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut. RE: Subtracting Hexidecimal TexFlex (Programmer) (OP) 25 Sep 08 15:35 Thank you for the reply. Now I realize I maybe having a little trouble with hex. Do you know of a website that I could go to to strengthen my knowledge in hex.Thank you RE: Subtracting Hexidecimal OlafBogus (Programmer) 26 Sep 08 06:54 As Salem says arithmetic in hexadecimal is the same as in decimal.Decimal is base 10, there are 10 symbols 0,1,2,3,4,5,6,7,8,9.10 in decimal is 1 ten and 0 units, 11 is 1 ten and 1 unit etc...Hexadecimal is exactly the same except its base is 16, there are 16 symbols 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F (A-F representing the numbers 10 – 15)10 in hex is 1 sixteen and 0 units, B in hex is 0 sixteen and 11 units, 2E in hex is 2 sixteen and 14 units.http://www.geocities.com/thestarman3/asm/hexawhat.html RE: Subtracting Hexidecimal TexFlex (Programmer) (OP) 26 Sep 08 13:21 Thank you OlafBogus,Now I clearly understand how hex works.
