	~~Explanation:~~
	~~Since both variables, weight~~ and nms_iou_threshold, are templated and finally boil down to a primitive type during compilation, it is meaningful to use a static_cast to convert the respective constant (1.0 (by default double) and 0 (by default int)) to the template type. Based on the operator candidates the required types should ~~all be compatible, i.e., the constant values are safe to be casted to the target template type.~~
