5. If S used in the 32-bit instruction is a string and the number of characters contained in the
string is less than 11, the characters which the string lacks are regarded as 0. The first
character is a sign character. If the first character is " " (a space), the sign is a positive sign. If
the first character is "-", the sign is a negative sign. Take the string "-0123456789" for example.

6. If the value in S is 16#20 or 16#00, the value is processed as 16#30.
7. If the sign character is 16#20, 16#30 or 16#2B, the conversion result is a positive value. If the
sign character is 16#2D, the conversion result is a negative value.
8. If S used in the 16-bit instruction is a string, the number of characters contained in the string
should be within the range between 1 and 6. If S used in the 32-bit instruction is a string, the
number of characters contained in the string should be within the range between 1 and 11.
Example 1:
Suppose the values in D20, D21, and D22 are 16#202D, 16#3220, and 16#3736. When the PLC
runs, the value in D0 is -267.

16#3836, 16#3733, and 16#3330. When the PLC runs, the value in D0 is 3968370.
