Hex Notation
Hex or base 16 is simple another base of counting. It is what you need to understand to use a ml monitor effectively and here I will explain.
You don't necessarily need to understand it, you just need to be able to use it. As you may have guessed, unlike our decimal system which uses tens, hex uses sixteens. (0-f) Her e is how to convert a decimal number to a hex number.
Say you wanted to convert 53280 to hex. You would start by making a chart like this.
4096 256 16 1
MMMMMMMMMMMMMMMMMMMMMM
Then, you take the first number-4096 and figure out how many times 53280 will go into it evenly.
It goes into it 14 time, or d in hex. So put a d on the chart.
4096 256 16 1
MMMMMMMMMMMMMMMMMMMMMM
d
Now proceed to do the same with the remaining three until you have the correct number.
256=0
16=2
1=0
Finish off your chart and whammo! For further info refer to the Commodore 64 Programmers Reference Manual. pg. 216-17.
