'real' is single precision, which is only about 6 digits of decimal
accuracy. if your java variables were double precision, you probably
should have used double in postgres too.
0.1 decimal is a repeating fraction in binary.
ooops, missed my third point. if precise decimal numbers are
important, use a decimal data type, which is NUMERIC in SQL (I'm not
familiar enough with Java to know if it has a BCD or other decimal type).
