    Default How would I compare the square of the square root of any number.

    How would I compare the square of the square root of any number. The difference in these values is due to the rounding error in Java.

    Example: Enter number 2

    The answer I should get is: 2.000000000000004
    Round off error: -4.440892

    The answers are estimated answers but are very close
