Please enter a FULL description of your problem:
------------------------------------------------
Evaluationg following SQL cause parse error.
It seems that there's a bug parsing negative floating value
that has more than 15 digits after the period.
> db1=> create table foo ( d float );
> CREATE
> db1=> insert into foo values ( -0.123456789012345 );
> INSERT 178112 1
> db1=> insert into foo values ( -0.1234567890123456 );
> ERROR: Unable to convert left operator '-' from type 'unknown'
> db1=> insert into foo values ( 0.1234567890123456 );
> INSERT 178113 1
> db1=> insert into foo values ( 0.12345678901234567 );
> INSERT 178114 1
This makes another problem because Java's Double.toString(double ) methods
returns the following expression, so JDBC's PreparedStatement.setDouble(int,double)
may fail.
>public class Test {
> static public void main(String args[]){
> double d = 1.0 / 7.0;
> System.out.println(d);
> }
>}

>% java Test
