• If the absolute value of the result is greater than the maximum value that can be expressed as float-
ing-point data, the Overflow Flag will turn ON and the result will be output as ±∞.
• If the absolute value of the result is less than the minimum value that can be expressed as floating-
point data, the Underflow Flag will turn ON and the result will be output as 0.
 Operation rules
The result of an operation is output as shown below depending on the combination of floating-point
data.
