NJ-series Instructions Reference Manual (W502)
**_BCD_TO_***
These instructions convert BCD bit strings into unsigned integers.
* The valid ranges depend on the data types of In and Out. Refer to Function, below, for details.
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 types of In and conversion result Out. For exam-
ple, if In is WORD data and Out is UINT data, the name of the instruction is WORD_BCD_TO_UINT.
The following example for the WORD_BCD_TO_UINT instruction is for when In is WORD16#3452.
