圆周率的计算

for k in range(N) :
	pi += 1/pow(16,k) * (4/(8*k+1) - 2/(8*k+4) - 1/(8*k+5) - 1/(8*k+6))
print("圆周率值是: {}".format(pi))

from random import random

DARTS = 1000*1000
hits = 0.0
start = perf_counter()
for i in range(1,DARTS+1) :
	x,y = random(), random()
	dist = pow(x ** 2 + y ** 2,0.5)
	if dist <= 1.0:
		hits = hits + 1
pi = 4 * (hits/DARTS)
print("圆周率值是: {}".format(pi))
print("运行时间是: {}".format(perf_counter() - start))
