How to factorial a number
Web1 Answer Sorted by: 25 The Factorial of a Rational number is defined by the Gamma function. A link is in the comments. Since, n! = n × ( n − 1)! Γ ( n) = ( n − 1)! n! = n ⋅ Γ ( n) Γ ( 1 2) = π So, 1.5! = ( 3 2)! = ( 3 2) ⋅ ( 1 2)! = ( 3 2) ⋅ ( 1 2) ⋅ Γ ( 1 2) = 3 4 π This can be useful.
