real-handling in .DBF-files

[jesper@…]

Hi There

Think I found a bug in the ogr2ogr tool (from inside the windows FWTools1.2.0):
when I try to convert an area that has large real-numbers, the sign is not treated as I expect. After convertion from source to targetfile (with only the affected area inside) the atribute-number 57520907013796 is ,. Same thing with FEATAREA. See the headers below (from ogrinfo):
-----------------------------------
Sourcefile (largebug_region.shp):
ID: Real (15.0)
FEATTYP: Integer (4.0)
FEATAREA: Real (15.0)
FEATPERIM: Real (15.0)
POSTCODE: String (10.0)
OGRFeature(largeitem_region):0
  ID (Real) =  57520907013796
  FEATTYP (Integer) = 3136
  FEATAREA (Real) =     11255420040
  FEATPERIM (Real) =         1202210
  POSTCODE (String) = 930

but in the target (using ogr2ogr largebug_target.shp largebug_region.shp) data looks like this
-----------------------------------
ID: Real (15.0)
FEATTYP: Integer (4.0)
FEATAREA: Real (15.0)
FEATPERIM: Real (15.0)
POSTCODE: String (10.0)
OGRFeature(largeitem):0
  ID (Real) =     -1589981532
  FEATTYP (Integer) = 3136
  FEATAREA (Real) =     -1629481848
  FEATPERIM (Real) =         1202210
  POSTCODE (String) = 930

Thought you wanted to know. Let me know if you need the test-file.
