I have to validate a float. I can type anything or nothing in and never see a validation problem when I set the depends attribute to "required, float". The field just ends up 0 upon save.
If I add a floatRange, it will complain at least complain if a number is outside of the range, but I don't need to enforce a range, since all floats are valid. Setting the validation to integer works, but I don't want that. Thanks.
