First a disclaimer. I am a new user of SQLITE and have not dug very
deeply into the code and literature, so my question may be trivial.
I have a system from an emulation of a legacy commercial language
processor which uses a very handy fixed point decimal number system.
The numbers are of arbitrary precision and held in right justified
display format. As you can imagine arithmetic on such numbers is not
blindingly fast but for general commercial usage they are truly
excellent. Commercial applications are not calculation intensive but
are display intensive so the time saved in radix transformation and
editing far exceeds the time lost in divisions.
This type of fixed point display format number with automatic rounding
makes it very easy to produce reports which balance to the penny and
incredibly easy to generate financial reports. Such a number type does
seem to fit in with the SQLITE concept of loose typing, since it is
actually just a text field.
There is actually an obscure ANSI standard which defines these numbers.
How feasible and how difficult would it be to add this type to SQLITE?
The numbers store as text strings so what is involved is adding the new
numeric type and inserting the arithmetic functions so that they are
recognized by the SQL processor?
If anyone has a quick answer I should appreciate it.
PS, with such fixed point numbers you would have 5.0 / 2.0 = 2.5 exactly.
