<-- Anonymously Posted: Tuesday, August 02, 2005 03:32 --> Hi, Does someone know what the correct range of the TERADATA FLOAT datatype? The DBS throws error "3755 Numeric overflow error" for float value 2x10**308. The V2R4.0 documentation says the range for the FLOAT data type is 2 x 10**-307 to 2 x 10**+308. thanks Phantom BTEQ 08.02.03c.00 Tue Aug 02 12:59:32 2005 +---------+---------+---------+---------+---------+---------+ sel * from dbc.dbcinfo; *** Query completed. 2 rows found. 2 columns returned. *** Total elapsed time was 1 second.
