The Factorial of a Rational number is defined by the Gamma function. A link is in the comments. Since, $n!=n\times (n-1)!$ $\Gamma(n)=(n-1)!$ $n!=n \cdot \Gamma(n)$ $\Gamma \left(\dfrac 12\right)=\sqrt\pi$

In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. Calculator to give out the factorial of a positive integer.
A first approach: when you evaluate the factorial of two consecutive integers, the factorial of the half-integer should lie somewhere in between. Due to the (super)exponential growth of the factorial, it makes sense to consider the geometric mean, and define $$(n+\frac12)!\approx\sqrt{n!(n+1)!}=n!\sqrt{n+1}.$$
