Example for BCD operating mode
For simulation purposes in easySoft 7, function block input I1 can be connected to a
marker double word instead of to a BCD source. The value of this marker double word
can be entered in hexadecimal or decimal format. It will always be interpreted as BCD
at function block input I1.

The most significant nibble determines the sign. For negative
numbers, the two's complement will be calculated.
Since each decimal value is represented with four bytes or eight
nibbles and each nibble in the BCD code can assume a value of
9, the largest number that can be represented is 9999999. The
smallest number that can be represented is -9,999,999.
