The type hiqdev\php\billing\type\TypeInterface was not found. Maybe you did not declare it correctly or list all dependencies?
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
The issue could also be caused by a filter entry in the build configuration.
If the path has been excluded in your configuration, e.g. excluded_paths: ["lib/*"],
you can move it to the dependency path list as follows:


filter:
    dependency_paths: ["lib/*"]

It seems like $sum->getQuantity() can also be of type string; however, parameter $num of floor() does only seem to accept double|integer, maybe add an additional type check?
                                                                                                                                                                                           (

 If this is a false-positive, you can also ignore this issue in your code via the ignore-type   annotation
