[sc-dev] precision of GAMMALN

2008-03-10 Thread Regina Henschel
Hello, the function GAMMALN is calculated with the Lanczos algorithm. The precision of the result depends on some coefficients. In the current version in OOo the coefficients give only a precision of up to 10 significant digits. I looked around for some better coefficient and found them in Apache
