Cześć, mam pewien problem z obliczaniem marż, pokazuje mi jakieś dziwne zawyżone wartości. Możecie rzucić okiem na kod?

nie chce mi się czytać kodu, bo najprawdopodobniej masz problem z przechowywaniem liczb w bazie (zapisujesz jako float zamiast decimal)

poczytaj, bardzo fajnie jest tutaj to wyjaśnione : KLIK

W bazie jest decimal
Już rozwiązałem problem. Ale i tak dzięki za chęć pomocy
