The Square Root Calculator is a simple online web-based tool that calculates the square root of a given number. It features an intuitive interface where users can input a number, click a button, and instantly see the result.

Example:

• Input: Enter 64 into the input field.
• Action: Click the “Calculate” button.
• Output: The result displayed will be: “The square root of 64 is 8.”

If you enter an invalid input (e.g., text or a number longer than 13 digits), you will see an error message such as “Please enter a valid number.”
