I.e. I suggest to replace high precision numeric's implementation using decfloat with native 128-bit integer when possible and ttmath in other cases. That will make it possible to use 128-bit integers in all cases when 64 is not enough without serious performance penalty. Comments?
Just to be sure: do you suggest to remove DECFLOAT implementation which you have been working on for several years?
BTW, does this piece of code really worth optimization? For example, I know a method for multiplication overflow prediction which is much faster than current one, but will it bring any noticeable change to Fiebird performance as a whole?
