====== Binary, Decimal, Hexadecimal ======

To program well, we need to know binary, decimal, and hexadecimal
numbers. The following chart shows the relationships between these
notations.

^Decimal ^Binary ^Hexadecimal^
|0 |0000 |0|
|1 |0001 |1|
|2 |0010 |2|
|3 |0011 |3|
|4 |0100 |4|
|5 |0101 |5|
|6 |0110 |6|
|7 |0111 |7|
|8 |1000 |8|
|9 |1001 |9|
|10 |1010 |A|
|11 |1011 |B|
|12 |1100 |C|
|13 |1101 |D|
|14 |1110 |E|
|15 |1111 |F|

In Cubloc’s Ladder Logic, we express binary and hexadecimal numbers in
the following manner:

    Binary: 00101010B
    Hexadecimal: 0ABCDH

We put a B at the end of the binary number and an H at the end for
hexadecimal numbers. To clearly identify that a hexadecimal value is a
number, we can put a 0 in front of the hexadecimal number. (E.g. : 0ABH, 0A1H, 0BCDH )

*BASIC is slightly different from Ladder Logic in the way binary and
hexadecimal numbers are expressed. &B100010 is used for binary and
&HAB is used for hexadecimal.
