Are you agree with that ?

```PHP
//APY\DataGridBundle\Grid\Column\NumberColumn
foreach($parentFilters as $filter) {
            if(is_array($filter->getValue())){
                $value = $filter->getValue();
                $filter->setValue(reset($value));
            }
            // Transforme in number for ODM
            $filters[] = ($filter->getValue() === null) ? $filter : $filter->setValue($filter->getValue() + 0);
}
```
