LD
REAL#45
Additional Information
Use the CheckReal instruction (page 2-209) to see if Out is positive infinity, negative infinity, or nonnu-
meric data.
Precautions for Correct Use
• If the absolute value of the conversion result exceeds the maximum value of the data type of Out, the
value of Out will be positive or negative infinity.
• If the absolute value of the conversion result is lower than the minimum value of the data type of Out,
the value of Out will be 0.
• Make sure that the data type of Out is equal to or larger than the data type of In.
• If the value of In is positive infinity, negative infinity, or nonnumeric data, the value of Out is as shown
below.
