Hi,
if the first characters are numerics, no need to use regexp, since mysql does
implicit conversion if you do calculations :

mysql> select '10.95 tiitti' from dual;
+--------------+
| 10.95 tiitti |
+--------------+
| 10.95 tiitti |
+--------------+
1 row in set (0.09 sec)

mysql> select '10.95 tiitti'+0 from dual;
+------------------+
| '10.95 tiitti'+0 |
+------------------+
|            10.95 |
+------------------+
1 row in set (0.02 sec)
