def pi(precision): One can approximate the value of pi by using the Leibniz formula (given below) that calculates a theoretically infinite sum. In practice, though, we run a finite summation where the larger the number of terms the better the approximation of pi. Given precision as a float, this function approximates the value of pi using the Leibniz formula. The function should stop the infinite summation when the improvement of the approximation becomes smaller than the provided precision. 0() 44 4 4 4 4 2k +1 1 3 5 7 911 Leibniz formula (source: http://forum.codecall.net/uploads/monthly 03 2012/post-80377-13333829507556.png) Assume: precision is a positive float value.
