Hello Kindly!
I used composer update zendframework/zend-filter command to update my local zend-filter component, and it is successfully updated to 2.9.1, according to the document https://docs.zendframework.com/zend-filter/standard-filters/#tofloat, it already has this filter since 2.9.0, however I can not find the ToFloat.php file in vendor/zendframework/zend-filter/src.
Even if I run the composer update command to update all the libs, still ToFloat not work. I guess there is something wrong with the document, maybe ToFloat filter is in the todo list.
Any one can confirm this?
