The simplest answer is - because it is only defined for n = 0 (0! = 1) and n > 0 (n! = (n-1)! x n).
A factorial of a positive integer n, is the product of all positive integers less than or equal to n. For example the factorial of 5 is: 5! = 5 x 4 x 3 x 2 x 1 = 120 0! is a special case that is explicitly defined to be 1. A factorial is denoted by n! (5! for this example)
If you're referring to the square root of a negative number, it's an imaginary number.
An integer is a positive or negative whole number.
It is because of the way in which positive and negative numbers are defined.
Nothing. Factorials are only defined for whole numbers (non-negative integers).
Nothing. Factorials are only defined for whole numbers (non-negative integers).
what is the value of negative n factorial ?
It is an indicator of the factorial function, which is defined for non-negative integers. 0! = 1 and for n > 0, n! = n*(n-1)! so that n! = 1*2*3* ... *n
The simplest answer is - because it is only defined for n = 0 (0! = 1) and n > 0 (n! = (n-1)! x n).
Coz the gamma function is singular for all negative integers. The factorial for negative integers is not defined.
import java.math.BigInteger; public class Factorial { public static void main(String[] args) { BigInteger n = BigInteger.ONE; for (int i=1; i<=20; i++) { n = n.multiply(BigInteger.valueOf(i)); System.out.println(i + "! = " + n); }

#include <iostream> using namespace std; int main() { int i, number=0, factorial=1; // User input must be an integer number between 1 and 10 while(number<1 number>10) { cout << "Enter integer number (1-10) = "; cin >> number; } // Calculate the factorial with a FOR loop for(i=1; i<=number; i++) { factorial = factorial*i; } // Output result cout << "Factorial = " << factorial << endl;
An integer is a positive or negative whole number.
A negative number is any quantity that is less than zero. Negative numbers are the direct result of the arithmetical operation of subtraction.
