Troubles wit DECIMAL(12,4)

[Bart Verstraete]

Got the following table:

|-----------------------|
| invoices              |
|-----------------------|
| id (bigint(20))       |
| invoice_date (date)   |
| total (decimal(12,4)) |
|-----------------------|

cpp code
connection & query stuff
...
...
...


mysqlpp::longlong id = (mysqlpp::longlong)row["id"];
mysqlpp::Date invoice_date = (mysqlpp::Date)row["invoice_date"];
double total = (double)row["total"] //Throws an exception: Tried to 
convert "6.3000" to a "d

to what other data type can I convert?
