IDL is not accurate enough! [message #62192]

Hi,

I've been having problems with IDL accuracy. I'm trying to perform
calculations using the gamma function. The problem is that it grows
VERY fast! Performing this calculation in double (namely gamma(x)/
gamma(y) with x and y big) yields the result: NaN...
Would it be possible to use a program like 'Mathematica' (or any
other) and to plug it in my ILD program? Some kind of CALL_EXTERNAL
that is to say. If it is possible, how can I do it and what is the
best program to use?

Thanks,
Noah
