Fast algorithms for computing the factorial - Stack Overflow
I found FastFactorialFunctions describing a number of algorithms for computing the factorial. . Unfortunately, the explanations are terse and I don't feel like sifting through line after line of source code to understand the basic principles behind the al

Is there any built-in factorial function in c++? - Stack Overflow
You kinda end up needing some sort of big int type if you care about the exact values of the factorial for non-trivial case. C++ doesn't have a big int type, so I imagine that's why no standard factorial function exists. –

Is there a method that calculates a factorial in Java?
Inside the factorial function,while N>1, the return value is multiplied with another initiation of the factorial function. this will keep the code recursively calling the factorial() until it reaches the N= 1. for the N=1 case, it returns N(=1) itself and all the previously built up result of multiplied return N s gets multiplied with N=1. Thus ...

Function for factorial in Python - Stack Overflow
def factorial(n): return 1 if n == 0 else n * factorial(n-1) One line lambda function approach: (although it is not recommended to assign lambda functions directly to a name, as it is considered a bad practice and may bring inconsistency to your code. It's always good to know. See PEP8.) factorial = lambda n: 1 if n == 0 else n * factorial(n-1)

python - Factorial in numpy and scipy - Stack Overflow
The answer for Ashwini is great, in pointing out that scipy.math.factorial, numpy.math.factorial, math.factorial are the same functions. However, I'd recommend use the one that Janne mentioned, that scipy.special.factorial is different. The one from scipy can take np.ndarray as an input, while the others can't.

javascript - factorial of a number - Stack Overflow
The code above first defines two variables, factorialNumber and factorial. factorial is initialized with 1. factorialNumber will get the result of the prompt (a number is expected) and then, using a cycle, in each step, factorial is multiplied with the index of the step, which is represented by i.

C# to calculate factorial - Stack Overflow
And if you are worried about the Factorial recomputation, just add some Memoize on the Factorial-Enumerable. This is the kind of code I like to see. This is the kind of code I like to see. – Awesomni.Codes

Python lambda function to calculate factorial of a number
Recursive Factorial is a function that will call itself, or be applied to itself, something like f(f). Let us set Factorial(n) to be f(f,n) and compute as follows: def func(f, n): # takes a function and a number, return a number. if n > 0 : return n * f(f, n-1) else : return 1
