isn't the basic conversion rule is two values with a same underlying type can be converted to each other' type? (another basic conversion rule is, if T implements interface I, the values of T can be converted to values of I) The underlying types of different numeric types are different. Golang just makes an exception/convenience to make it is possible to convert the values of these types to any of these types. And there is another exception, integer values can be converted to string, this is one-direction conversion. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
