Untyped bool, int, etc are the types of untyped constants: https://golang.org/ref/spec#Constants > when will go compiler use them? The compiler already uses them. > can you show in example? const i = 42 // i is untyped int const j = int(42) // j is int var f float64 = i // ok because i is untyped int var g float64 = j // compile error, type mismatch https://play.golang.org/p/pVZyvzLLSXM -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
