Limitations and common mistakes

A mathematical scenario based on your input values, not a forecast, quotation or professional recommendation. Use consistent units and verify assumptions.
Combined input is bounded to 150,000 characters; output text is bounded to 1.2 million characters. Some algorithms impose smaller limits, stated in their error messages.
Use a dot as the decimal separator and commas or spaces between numeric entries. The calculation uses floating-point arithmetic unless exact integers are explicitly stated.
