Dear all, What are the limits of float8? The user guide says variable-precision, 14 decimal places range but I'm not sure how that translates to a minimum value. I'm asking because I'm storing probability scores (range 0 to 1) with some scores very small indeed. The very small scores are all entered in scientific notation. >From experimentation, the smallest value I seem to be able to enter is around 2.225e-308. Is this 'correct'? This is PG 6.4 compiled with cc under Irix 5.3.
