Converting Hexadecimal numbers to decimal numbers.

Hexadecimal digits go from 0 to F:  0-9, A-F
A = 10; B=11; C=12; D=13; E=14; F=15.

Converting from hexadecimal to decimal is pretty easy...even if the numbers are very long.

6F

Start with 0.  Then repeat this process:  multiply 16 and add the next digit.

0 x 16 + 6 = 6
6 x 16 + 15 = 111

0 x16 + 1 = 1
1 x 16 + 0 = 16
16 x 16 + 2 = 258
258 x 16 + 4 = 4132
4132 x 16 + 10 = 66122
66122 x 16 + 3 = 1057955

The only number you have to multiply by is 16.  And we know how to do that.  Just double the number 4 times.

ALL YOUR BASE ARE BELONG TO US

All files should begin with your name and a brief description of what this file contributes to the overall program.

The main file should also state what the program does as a whole.

All classes and methods should begin with a brief description of what they do.

As far as documenting your lines of code, this is largely unnecessary.  Only do this if you are doing something not obvious.

x = 5; //sets x to 5

numberofappletreesinmyyard = 7;

tednugent = 7; <== bad variable name



1057955 / 16 = 66122 r 3
66122 / 16 = 4132 r 10
4132 / 16 = 258 r 4
258 / 16 = 16 r 2
16 / 16 = 1 r 0
1 / 16 = 0 r 1
