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.
However, since a BCD source cannot represent negative numbers, a negative numeric
conversion at QV is simply a theoretical case.
Values greater than 9999999 are output as 161061273.
Values less than –9999999 are output as –161061273.
The working range of the function block has been exceeded.
