Square Root Calculator

1. The square root calculator is used to find the square root of the number you enter.

2. A square root, also known as a second root, is denoted by [√], and the square root of a non-negative number is called the arithmetic square root.

3. A positive number has two real square roots, which are opposite to each other; 0 has only one square root, which is 0 itself; a negative number has two conjugate purely imaginary square roots.

4. "√" is used exclusively to denote the arithmetic square root, i.e., the square root of a non-negative number. For example: √16 = 4.

5. Examples: The square root of 25 is 5; the square root of 2 is approximately 1.41421356237; the square root of Pi (π) is approximately 1.77245385102.
