FACTORIAL (Number)


  • is any positive integer.

Description

  • This function is showing the result of factorial of a number.
  • Factorial means the result of multiplying a sequence of descending natural numbers down to 1.
  • In  ,  is any positive integer.
  • So the factorial   is defined for a positive integer n as:

 .

  • For example 4!=4*3*2*1 = 24.
  • The given number will truncated to integer if the given number is in Decimal.
  • This function will returns the result as NaN when the given number is in negative.

Examples

  1. FACTORIAL(9) = 362880
  2. FACTORIAL(4.3) = 38.0779764499523
  3. FACTORIAL(54) = 2.308436973392414e+71
  4. FACTORIAL(-3) = Infinity
  5. a=(5!)! = 6.689502913449128e+198
