本文实例讲述了python计算圆周率pi的方法。分享给大家供大家参考。具体如下:
- from sys import stdout
- scale = 10000
- maxarr = 2800
- arrinit = 2000
- carry = 0
- arr = [arrinit] * (maxarr + 1)
- for i in xrange(maxarr, 1, -14):
- total = 0
- for j in xrange(i, 0, -1):
- total = (total * j) + (scale * arr[j])
- arr[j] = total % ((j * 2) - 1)
- total = total / ((j * 2) - 1)
- stdout.write("%04d" % (carry + (total / scale)))
- carry = total % scale
运行结果如下:
