O.o saya quote dari halaman itu, sepertinya memang disarankan pake decimal untuk jaga presisi "The DECIMAL and NUMERIC types store exact numeric data values. These types are used when it is important to preserve exact precision, for example with monetary data" Andi Malik Rizki Maula 9:15am Nov 11 btw saya tes decimal pake 40 digit tetep bisa om, makin bingung saya :v
