Additional Information
To convert data with any data type to a real number, use a TO_** (Real Number Conversion Group)
instruction (page 2-310).
Precautions for Correct Use
• Always use the correct instruction name for the data types of In and Out.
• If the value of In is positive or negative infinity, the value of Out is positive or negative infinity.
• If the value of In is nonnumeric data, the value of Out is nonnumeric data.
• If the conversion result exceeds the valid range of Out, the value of Out will be infinity with the same
sign as the value of In.
• For the LREAL_TO_REAL instruction, if the value of In is closer to 0 than ±1.175494e−38, the value
of Out will be 0.
