2 Instruction Descriptions
2-236
NJ-series Instructions Reference Manual (W502)
The following table shows the valid ranges for In and Out according to their data types.
• To convert a bit string to an integer, use a **_TO_*** (Bit String-to-Integer Conversion Group) instruc-
tion (page 2-239).
• To convert data with any data type to a bit string, use a TO_** (Bit String Conversion Group) instruc-
tion (page 2-279).
• Always use the correct instruction name for the data types of In and Out.
• If In is a signed integer and the data size of Out is larger than the data size of In, sign extension is
performed.
• If In is an unsigned integer and the data size of Out is larger than the data size of In, the upper digits
of Out will contain 0.
• If the data size of Out is smaller than the data size of In, the upper digits are truncated in Out.
