I want to make an app that calculates pi to any decimal place, even 1,000,000. I don't care how long it takes the computer. I know the formula for pi is as follows:
pi / 4 = 4 * tan-1(1 / 5) - tan-1(1 / 239)
However, I am at a loss of how to do this.
pi / 4 = 4 * tan-1(1 / 5) - tan-1(1 / 239)
However, I am at a loss of how to do this.
