Additional Information
• To convert a real number to a bit string, use a **_TO_*** (Real Number-to-Bit String Conversion
Group) instruction (page 2-249).
• To convert data with any data type to a real number, use a TO_** (Real Number Conversion Group)
instruction (page 2-281).
Precautions for Correct Use
• Always use the correct instruction name for the data types of In and Out.
• Depending on the data types of In and Out, rounding will be performed for the effective digits of the
real number. This will cause error between the values before and after conversion. The following table
lists the data types that result in error.
