* between 0 and 9, another addtional part starting with a dot (not a comma!) and followed by
* one or more chars with a value between 0 and 9.
*
* Note: To check if a value contains numeric chars/digits only, see DefaultValidator::digit().
*
* Note: As this only accepts a dot as decimal separator you should use the filter "float"
* (Defaultfilter::float()) before.
