Operation Description
Converts the stored string starting at D0200 to a decimal and stores the result in D0100.
The number of digits that can be converted is the maximum number of digits for each data type with added sign.
If the string to convert contains a NULL or characters that cannot be converted to numeric values, the string is converted up to
that character.
Notes:
•
This function can be used with data types W (word), I (integer), D (double word), and L (long).
•
The NULL terminating character (0x00) is added to the end of the string.
