Click the green flag, then enter the amount of terms in the convergent series you'd like the program to use to find pi. The higher the amount of terms you enter, the more the series will converge and the more accurate pi will be, but the longer the engine will take to calculate your answer. Turbo mode doesn't make this project calculate pi faster. I recommend that you have the engine use 1,000,000 terms, as this reaches the limit of how large pi can be due to size limits (see notes and credits). Plus, it takes only five seconds to calculate.
Image credit: Wikipedia I used a formula I found off Google to find pi's value. This is the formula: Pi = 3 + 4 / (2*3*4) - 4 / (4*5*6) + 4 / (6*7*8)... There are more accurate, but complex, formulas to find pi, but they involve summations, exponents, and factorials, which unfortunately cannot easily be recreated on scratch. This simple formula also can only calculate the first 14 digits due to Scratch's limit to how small numbers can be. But still, happy Pi Day!
