The following example is for when In is REAL data with a value of REAL#−123.456.
The following example is for when In is LREAL data with a value of LREAL#−123.456789.
The following table shows the valid ranges for Fraction according to the data types In and Fraction.
Use the UniteReal instruction (page 2-421) to combine a signed mantissa and exponent to form a real
number.
• Depending on the value of In, error may occur in the conversion to an integer.
