GAMMALN

Returns the natural logarithm of the gamma function.

Syntax:

GAMMALN(x)

returns the natural logarithm of Γ(x), the gamma function.
x must be greater than 0.

Example:

GAMMALN(4)

returns approximately 1.79.

Issues:

  • The forthcoming international standard ODFF categorises this as a mathematical function, and includes a GAMMA function which Calc does not currently implement.
