Can you take a factorial of a non integer?

Besides nonnegative integers, the factorial can also be defined for non-integer values, but this requires more advanced tools from mathematical analysis. Its relation to the factorial is that n! = Γ(n + 1) for every nonnegative integer n. The pi function and gamma function are related by the formula Π(z) = Γ(z + 1).

Does a factorial have to be an integer?

Factorial, in mathematics, the product of all positive integers less than or equal to a given positive integer and denoted by that integer and an exclamation point. Thus, factorial seven is written 7!, meaning 1 × 2 × 3 × 4 × 5 × 6 × 7. Factorial zero is defined as equal to 1.
