Getting an answer despite exiting recursioni wrote this python code, which from wolfram says that its supposed to return the factorial of any positive value (i probably messed up somewhere), integer or not: Code:from math import * def double_factorial(n): if int(n) == n: n = int(n) if [0,1].__contains__(n): return 1 a = (n&1) + 2 # checks if its even or odd and starts the a value at 2 or 3 b = 1 while a<=n: b*=a a+= 2 return float(b) else: return factorials(n/2) * 2**(n/2) *(pi/2)**(.25 *(1+cos(n * pi))) # go to the next definition def factorials(n): return pi**(.5 * sin(n*pi)**2) * 2**(n + .25 * (1 + cos(2*n*pi))) * double_factorial(2*n) # go back up the problem is , say i input pi to 6 decimal places. 2*n will not become a float with 0 as its decimals any time soon, so the equation turns out to be Code:pi**(.5 * sin(n*pi)**2) * 2**(n + .25 * (1 + cos(2*n*pi))) * double_factorial(loop(loop(loop(...))))) how would i stop the recursion and still get the answer?
