4 15 Babylonian Square Root Method Before calculators and computers, the square root of a number had to be computed by hand. One of the methods that was used to compute the square root was the Babylonian method (also known as the Hero's method). Here's how it works: Suppose I am trying to find the square root of 20, and I want the error value to be 0). Perform input validation to check the number entered Call a method called babSqrt to performs the process The method should accept and return a floating point value. .Keep the default guess as 1. i. In your method, you can set nextguess 1, so that you can repeat steps 2 3 and 4 easily. You can even write step 4 before steps 2 and 3! The method needs a loop to repeat the process (a do while loop is best). . i. Remember, you cannot compare floating point values using the operator. So you must use I nextguess -prevguess 0.00001 as your
