#841 Export to excel results in strange rounding
Exporting the following query to Oracle 10g DB using SquirelSQL 3.0.3 and 3.1 :
select 16770001, 16775001, 16776501, 16777001, 16777201, 16777241, 16777251, 16777261, 16777271, 16777281, 16777291, 16777301, 16777401 from dual
result in a strange rounding of the values:
16770001 16775001 16776501 16777001 16777201 16777241 16777251 16777261 16777271 16777281 16777291 16777301 16777401
16770001 16775001 16776501 16777001 16777201 16777240 16777252 16777260 16777272 16777280 16777292 16777300 16777400
Strangely the header can be displayed properly.
