About calculation errors
An error indicator appears on the display and further calculation becomes
impossible whenever an error occurs.
Any of the following conditions produces an error.
• Whenever the number of digits in the mantissa of an intermediate or
final result exceeds 12
• Whenever the number of digits in the mantissa of a value in calculator
memory exceeds 12 digits. In this case, the PV Unit automatically retains
the last value stored that did not exceed 12 digits.
• Division by zero
• Attempting to calculate the square root of a negative value
