How to Use the Racine Carrée Calculator
A Racine Carrée Calculator (or Square Root Calculator) is a digital tool that calculates the square root of a given non-negative number instantly.
What Is a Square Root?
The square root of a number is a value that, when multiplied by itself, gives the original number. For example:
- √16 = 4 → because 4 × 4 = 16
- √100 = 10 → because 10 × 10 = 100
Square roots are commonly used in:
- Geometry (e.g., Pythagorean theorem)
- Physics (e.g., calculating acceleration)
- Finance (e.g., volatility in stock returns)
- Everyday tasks like construction, design, and computing distances
Step-by-Step: Using the Calculator
- Enter a non-negative number (e.g., 144) into the input box.
- Click the “Calculate Square Root” button.
- The calculator will display:
- The original number you entered.
- Its square root, rounded to 5 decimal places.
This tool works instantly and can be used repeatedly just by changing the input.
Example Calculations
- Input:
25→ Output:5.00000 - Input:
