⭐ How This Square Root Calculator Works

The calculator uses the built-in JavaScript Math.sqrt() method. This method returns the positive square root of any real number.

• If the number is positive, the result is a normal real value.
• If the number is zero, the result is 0.
• If the number is negative, JavaScript cannot return a real number, so the tool shows a complex number with “i”, also known as an imaginary result.

This makes the calculator useful for both basic and advanced math.

🧪 Method Used: JavaScript Math.sqrt()

The main method used is:

Math.sqrt(number)

This method:

• returns the square root of any positive number
• returns NaN for invalid input
• helps detect negative numbers so we can convert them into imaginary values (i)

This is why the calculator is accurate, fast, and easy to use.
