BCD_TO_**
The BCD_TO_** instruction converts BCD bit strings into unsigned integers.
*1 The valid ranges depend on the data types of In and Out. Refer to Function, below, for details.
*2 If you omit the input parameter, the default value is not applied. A building error will occur.
These instructions convert data to convert In (which must be a BCD bit string) into an unsigned integer.
The name of the instruction is determined by the data type of conversion result Out. For example, if Out
is the UINT data type, the instruction is BCD_TO_UINT.
The following example for the BCD_TO_UINT instruction is for when In is WORD#16#3452.
