1. What is the Rainfall Totals Calculator?

The Rainfall Totals Calculator calculates the total rainfall over a specified period by summing daily rainfall measurements. This is useful for hydrology studies, agriculture planning, and water resource management.

2. How Does the Calculator Work?

The calculator uses the simple summation formula:

Where:

• \( daily\_rainfall \) — Array of daily rainfall measurements (inches)
• \( \sum \) — Summation operator
• \( total \) — Cumulative rainfall total (inches)

Explanation: The calculator simply adds up all the daily rainfall values you provide to give the total rainfall over the measurement period.

3. Importance of Rainfall Calculation

Details: Accurate rainfall totals are essential for flood prediction, drought monitoring, crop irrigation planning, and water supply management.

4. Using the Calculator

Tips: Enter daily rainfall values separated by commas (e.g., "0.5, 1.2, 0, 0.3"). All values must be non-negative numbers. The calculator will ignore any invalid entries.

5. Frequently Asked Questions (FAQ)

Q1: What units does this calculator use?
A: The calculator uses inches by default, but you can use any unit as long as all values use the same unit.

Q2: How many values can I enter?
A: You can enter as many values as needed, separated by commas.

Q3: What if I have missing data?
A: For missing days, you can enter 0 or leave blank between commas (e.g., "0.5,,0.3" would treat the middle day as 0).

Q4: Can I calculate monthly averages?
A: This calculator only provides totals. For averages, divide the total by the number of days.

Q5: Is there a limit to the decimal precision?
A: The calculator handles values with up to 4 decimal places and rounds results to 2 decimal places.
