Can Decimal numbers have Factorials?
In general, you don’t. The factorial function is defined on natural numbers, like 1, 2, 3, and so on. It is not defined on rational numbers like 1.7, or real numbers like .
How do you find the factorial of a decimal?
1 Answer
- n! =n×(n−1)!
- Γ(n)=(n−1)!
- n!= n⋅Γ(n)

Do Factorials only work for integers?
n! 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: For example, The factorial function can also be extended to non-integer arguments while retaining its most important properties by defining x!
What is negative factorial number?
The factorials of real negative integers have their imaginary part equal to zero, thus are real numbers. Similarly, the factorials of imaginary numbers are complex numbers. The moduli of the complex factorials of real negative numbers, and imaginary numbers are equal to their respective real positive number factorials.
Do negative numbers have factorials?
As per the present concept, the factorials of real negative numbers, are complex numbers. The factorials of real negative integers have their imaginary part equal to zero, thus are real numbers.
Can a factorial be odd?
The term odd factorial is sometimes used for the double factorial of an odd number.
Where are Factorials used?
It is common to use Factorial functions to calculate combinations and permutations. Thanks to the Factorial you can also calculate probabilities.
Is factorial defined for negative numbers?
Factorial is defined only for non-negative integer numbers . Factorial can be interpolated using Gamma function, hence we can have factorial of a negative number except for negative integers because gamma function is not defined at negative integers. Originally Answered: what is factorial of (-3)?
