S - shows the x and y variables H - hides the x and y variables R - resets everything and allows a new input
Put in a number above 0 and the square root will be calculated as quickly as possible. The answer may not always show up since Scratch goes up to 14 decimal places and so small errors may occur, if this happens, I recommend pressing S to show the x value although that only goes to 6 decimals. The formula used for this x = (x+(y/x))/2 and is repeated until the number doesn't change. (it does this by keeping the 2 most recent answers and if they are the same, it stops.) Credit to primexandy for the formula. (They showed it on their calculator although it is slightly slower due to the text loading.
