>>>ATTENTION!<<< DUE TO THE INCAPABILITY OF SCRATCH TO PRODUCE LARGE DECIMALS, THIS PROJECT DOES NOT WORK VERY WELL. Hit any key to type in the accuracy factor, and π will be calculated to that degree.
I came up with this equation myself, and I was hoping it would work on Scratch. But Scratch rounds decimals, so the output will always be rounded. The equation is: π = (∞tan(360/∞))/2 This equation involves infinity, but in place of infinity, you can use a number multiple of 10. The larger the number, the more accurate the answer is. The accuracy factor in this project is automatically put to the power of 10, so the input for this project does not need to be a multiple of 10.
