# GAMMALN

### Definition of GAMMALN

Returns the the logarithm of a specified Gamma function, base e (Euler's number).

### Sample Usage

`GAMMALN(4)`

`GAMMALN(A2)`

### Syntax

`GAMMALN(value)`

`value`

- The input to the Gamma function. The natural logarithm of Gamma(`value`

) will be returned.`value`

must be positive.

### Notes

Excellentable does not support complex or imaginary values.

`GAMMALN`

is used for certain types of analysis or as a component to other functions and is rarely used by itself.
