If you read the manual for settype(), you will see that the return value
is a Boolean, TRUE for success, FALSE for failure. $bedrag itself will
have its type changed.
Note also (although this won't affect the operation) that "double" is
deprecated as of PHP 4.2.0. Use "float" instead.
Alternatively, use $nieuw = floatval($bedrag);

Why put it in string, why not just $demo = 16.60 ??
