GAMMAFUNCTION (z)


  • is any positive real number.

Description

  • This function gives the value of the Gamma function.
  • The Gamma function is defined to be an extension of the factorial to complex and real number arguments.
  • That is, if n is a positive integer:

  • Gamma function is defined for all complex numbers except the non-positive integers.
  • For complex numbers with a positive real part, it is defined via a convergent improper integral:

  • This function will return the result as NaN when the given number as negative or Non numeric.


Examples

  1. GAMMAFUNCTION(2) = 1.0000026676984093
  2. GAMMAFUNCTION(45.3) = 8.308990531109891e+54
  3. GAMMAFUNCTION(-3) = #N/A (#NUM!)
