### Description

Returns the natural logarithm of the gamma function, Γ(x).

### Sample Usage

### Syntax

GAMMALN.PRECISE(x)

The GAMMALN.PRECISE function syntax has the following arguments:

If x is nonnumeric, GAMMALN.PRECISE returns the #VALUE! error value.

If x ≤ 0, GAMMALN.PRECISE returns the #NUM! error value.

The number e raised to the GAMMALN.PRECISE(i) power, where i is an integer, returns the same result as (i - 1)!.

GAMMALN.PRECISE is calculated as follows:

*GAMMALN.PRECISE* = *LN*(Γ(*x*))

where:
