GAMMALN(x)
The GAMMALN function calculates the natural logarithm of the gamma function at a given value. For example, =GAMMALN(4) returns the natural logarithm of the gamma function at 4.
The GAMMALN function can be used to calculate the natural logarithm of the gamma function of any real number. For example, =GAMMALN(7.5) returns the natural logarithm of the gamma function at 7.5.
The GAMMALN function can be used to calculate the natural logarithm of the gamma function of any positive integer. For example, =GAMMALN(5) returns the natural logarithm of the gamma function at 5.
The GAMMALN function can be used to calculate the natural logarithm of the gamma function of any fractional number. For example, =GAMMALN(1/2) returns the natural logarithm of the gamma function at 1/2.
The GAMMALN function calculates the natural logarithm of the gamma function Γ(x), which requires an argument x. It is calculated using an integer to calculate the power of e.
