Joost,  look at ftBCD, ftCurrency they are also written as floats
So if there is it acceptable, then I would say, that also in this case 
is it acceptable, isn't it ?
(I do not say, that it is perfect)

Patch is attached.

DECIMAL -> ftBCD (if precision and scale is not supplied, then scale=0)
DECIMAL(p) = DECIMAL(p,0) = DECIMAL(p,<nonnumeric>) -> if p<=18 then 
ftLargeInt else ftFmtBCD
DECIMAL(p,s) -> if s>4 or p-s>14 then ftFmtBCD (number does not fit into
