FACT/FACTDOUBLE with fractions

[Eike Rathke <erack@sun.com>]

Hi,

FACT and FACTDOUBLE have

| TBD: Should we mandate that it compute INT() first? Excel 2002 computes
| the INT() of the parameter first, and then computes the factorial. It'd
| be more flexible if we allowed fractional values. This has been reworded
| to note that it's only REQUIRED to support integer parameters, and then
| permitting GAMMA() for fractional values.

For interoperability we should not allow fractionals. Opinions?

Btw, which applications do support GAMMA?
