A strange thing I noticed with this is that
"select -234567890.1234567;" works and
"select -1234567890.123456;" also works while
"select -1234567890.1234567;" does not. That
extra character just seems to push things over
the edge.
It almost seems like there is some sort of length
restriction somewhere in the parser.
