Documentation/How Tos/Calc: GAMMA function
Returns the values of the Gamma function.
- x is a number.
- Constraint: If x is an integer, then x must be positive.
|GAMMA(4) = 6.0 exact
GAMMA(34.56) ≈ 6.2336323276E+037
GAMMA(−4) not defined
For x < 0.5 Eulers reflection formula is used.
The Gamma function has poles for negative integers and for zero. Near the poles the values are less accurate.
If x is a positive integer, then
But be aware, that OpenOffice.org has only a precision of 15 digits and results, which would consists of more than 15 significant digits, are rounded.
This function is expected for OOo3.1. Issue 94555
