Fixed. ODBC make we confused with SQL_C_FLOAT (32bit) and SQL_FLOAT (64bit).
I changed all code to not use SQL_FLOAT but only SQL_DOUBLE (two constant
for the same type... I don't understand the reason!).

This is precision problem... perhaps tsql do different rounding...
Thanks for all your testing... I have to add another test now...
