It's not the definitive default number only because performance reasons and because of C influence in language design. If most languages had Decimals, I am sure only C/C++/Java diehards would use ints/floats instead. In fact most modern scripted languages should have them. Regarding go, as it is a relatively new language, and having to interact with databases, with Decimal being a fundamental SQL type, yes, it should have Decimal.
