You can set the "accuracy" of the bignum module. Read "perldoc bignum"

BTW, if you make fact() recursive and use the Memoize module, you can

Thanks all of you.
This trick really really improve speed.

But if there is no previous knowledge that all numbers will be
integers

Aren't Catalan numbers only defined on integers?

I can not fix the precision or accuracy.

Choosing to leave the defaults in place is still a choice, and you should
understand what the consequences of that choice are. It is not for the
accuracy and precision to be infinite. They are still limited through
some confusing fall-back method.
