How far off do you reckon it is from being "production" ready?

Asking because we've been adding useful SQLite extensions as optional extras in our (sqlitebrowser.org) installer. Can add yours too, if you reckon the code is reasonably cross platform and shouldn't cause (many) weird issues. :)

As in other database systems such as Postgres. Even a C# style decimal floating point type would be sufficient.

Basically--it's a struct containing a byte array, weight, scale, and sign, and all the arithmetic operations are implemented in software. So it's really slow, and each RDBMS has to implement this type from scratch, or find a vendor lib that provides a suitable one, because C/C++ standard libraries don't provide one.

No, that's just an alias for numeric type affinity which results in a binary floating point type if there's a decimal point.

There's also a long tradition of "faking" decimals with integers. I have always found that to be extremely tedious and error prone.
