there is no such factorial it's out ofmaths rules

factorial by def. is for natural numbers. and 0!=1 by def.is added to it.

There is a way to calculate factorial of any number by using what's called Gamma function
gamma(z)=definite integrala 0 to infinity (t^(z-1) * e^(-t) dt

and the relation between gamma function and factorial is
gamma(x+1)=x!

so 2.4!=gamma(3.4)=2.98120642681

We can not find factorials for those type(a/b) of numerical values.

The factorial n!(say) gives the number of ways in which n objects can be permuted(arranged). There will be 2 objects or 3 objects but not 2.4 objects.

I want to make clear for you that, the factorial is applicable for the positive whole numbers only and for other numerical values.

Hope you got the correct answer.
thanks

First, I agree with the answer that factorials are only define  for natural numbers.

There is however, the Gamma function from statistics.

Gamma(t) = (integral from 0 to infinity)(e^(-x)x^(t-1)dx

Has the property that Gamma(n+1) = nGamma(n) = n!.

rt11guru gave the first right answer of any of these.

Factorial only applies to integers.  But the Gamma function has the same behavior, and isn't restricted to just integers.

So  the question reduces to [2.4]!
