## Square Root Curve Calculator

**How to Use:**
To use the square root curve calculator, simply enter any positive number or zero into the input field and click the “Calculate” button. The calculator will compute the square root of the number you entered and display the result in the adjacent field.

**How it Calculates:**
The calculator uses the square root function from JavaScript’s Math object, which takes a number as input and returns its square root. If you input a negative number, the calculator will tell you that the input is invalid, as the square root of a negative number is not a real number (it’s an imaginary number).

**Limitations:**
This calculator works with any non-negative real number. It does not accept letters or special characters. Due to the limitations of numeric precision in computing, the calculator may not be able to accurately compute the square root of extremely large numbers or numbers with a high number of decimal places.
