Add item:

> * Add NUMERIC division operator that doesn't round?
>
> Currently NUMERIC _rounds_ the result to the specified precision.
> This means division can return a result that multiplied by the
> divisor is greater than the dividend, e.g. this returns a value > 10:
>
> SELECT (10::numeric(2,0) / 6::numeric(2,0))::numeric(2,0) * 6;
>
> The positive modulus result returned by NUMERICs might be considered
> inaccurate, in one sense.
