Factorial of a number

Function: Factorial of a number

This function helps you calculate the factorial of a given whole number. A factorial is the product of an integer and all the integers below it. For example, the factorial of 4 (written as 4!) is 4 × 3 × 2 × 1 = 24. The factorial of 0 is defined as 1.

Input,

  • Base: The whole number for which you want to calculate the factorial. This input is required.
    • Type: Number

Output,

  • Result: The calculated factorial value of the provided 'Base' number.
    • Type: Number

Execution Flow,

Real-Life Examples,

  1. Calculate the factorial of 5

    • Inputs:
      • Base: 5
    • Result: The Result variable will hold the value 120 (since 5! = 5 × 4 × 3 × 2 × 1 = 120).
  2. Calculate the factorial of 0

    • Inputs:
      • Base: 0
    • Result: The Result variable will hold the value 1 (by mathematical definition, 0! = 1).
  3. Calculate the factorial of 7

    • Inputs:
      • Base: 7
    • Result: The Result variable will hold the value 5040 (since 7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040).
