IF, just IF, someone were to implement such a thing what major math operators need to exist ?
+, -, *, / obviously
what else would YOU need for applications to make such a type useful ?
Mod, Floor, Celing. Not sure if those count.
Guess I had in mind financial type apps for BCD
Cant say I ever used those but … I’ll see what I can do
Some rules for electronic invoicing in Mexico include calculations with pow and sqrt. Same rules use rounding and tuncating.
I’ll see what I can do about those
For financial calculations, Banker’s round.
Should be quite doable 
I’ve got most of the things people have mentioned already
I probably should know this, but how is this different from System.Decimal in .NET?
If he is doing it from scratch because the tool dont have a decent BCD data type, must be for xojo 
I’m not writing this for .Net 
Winna Winna Chicken Dinna !!
Turns out I’ll end up needing this since Currency is inadequate
And scaling an Int64 leaves me without enough precision
So I needed “something else”
