Uh, could you please be specific? What "algorithms" are inaccurate? Most
of the code is inherited from previous versions of Postgres, but I have
done extensive work on the input/output formats, internal storage,
adding a circle data type, comparison operators, and conversion
operators between types.
Most math is double precision float, so should be fairly accurate in
principle. However, older versions of Postgres had at least some
floating point operations rounded to 7 digits for purposes of
comparisons!?! Made the regression tests and low precision work easier,
but...
