gisdb=# select asText('POINT(1E-100 2)'::geometry);
     astext

 POINT(1e-100 2)

So PostGIS is capable of reading and writing scientific notations.

The PostGIS JDBC driver extension relies on JTS WKTWriter/Reader for JTS
 I/O, and supports scientific notation for its own class model (where I
just committed a regression test case).


HTH,
Markus
