```    I'm trying to multiply numbers one of which is money. The money
looks like this:

SELECT price FROM titles;

| price  |
+--------+
| \$20.00 |
| \$19.99 |
| \$7.99  |
| \$19.99 |
| \$11.95 |
| \$19.99 |
| \$14.99 |
| \$11.95 |
| \$22.95 |
| \$2.99  |
| \$10.95 |
| \$7.00  |
| \$2.99  |
| \$20.95 |
| NULL   |
| \$19.99 |
| \$21.59 |
| NULL   |
+--------+
18 rows in set (0.01 sec)

When I use SELECT title_id, ytd_sales * price From titles;

I get:
| title_id | ytd_sales | price * ytd_sales |

It appears that mysys 4.1 does not know how to multiply a dollar
amount to another number. Has anyone else seen this problem?
