Re: Rounding errors in financial app transforms

On the other hand if you really want to emulate BCD arithmetic exactly it's probably not too hard to come up with a set of xsl functions that do that using integer internally. > My guess is that even having a standard MulDiv function in XSLT > wuld help matters floating-point-wise but sadly there is no such > animal available. Not really thought about it, but if doing decimal or integer arithemtic rather than double arithmetic, isn't muldiv the same as the naive operation of doing the multiplication and then dividing?
