I am writing a code for the factorial function. My code is as follows: > f<- function(n){+ factorial <- 1+ if( n < 0 )+ print("Factorial of negative > numbers is not possible")+ else if( n == 0 )+ print("Factorial of 0 is 1")+ > else {+ for(i in 1:n)+ factorial <- factorial * i+ print(paste("Factorial of > ",n," is ",factorial))+ }+ }
My problem with this code is for decimal numbers as input. For example for f(6.5) my code computes 720, but we know 6.5 ! does not exist. For decimal numbers like, or sqrt(2) I would like to see a message like "The factorial for this number does not exist". How can I fix this problem in my code?
