I want to make a small python script to calculate pi to N number of decimal points and then only output that number of decimals. I don't know how to change the print statement to dynamically limit the number of outputted decimals. Here's my code.
#!python
import math
N = input("Enter the number of digits of pi you would like to compute: ")
runs = math.ceil(N/math.log(2))
a_0 = 1.0
b_0 = 1.0/(2.0**(1.0/2.0))
t_0 = 1.0/4.0
p_0 = 1.0
for x in xrange(1,N):
a = (a_0 + b_0)/2
b = (a_0*b_0)**(1.0/2.0)
t = t_0 - p_0*(a_0 - a)**2
p = 2*p_0
pi = ((a_0 + b_0)**2)/(4*t)
print pi
a_0 = a
b_0 = b
t_0 = t
p_0 = p
print 'Pi to %d number of digits is: ' % (N)
print "%0" N "d\n" % pi
I know my last print statement isn't how you implement this feature, but it gives an idea of how you might do it in something kinda like C.
I just want that last print statement to output pi to N number of digits.
