Go overflows int64
WebFeb 1, 2014 · Where int32 is 32 its integer type, int64 is 64 bits and the size of the generic int type is platform dependent. It is 32 bits wide on a 32-bit system and 64-bits wide on a 64-bit system. So we must be careful and specific while specifying generic data types like … WebJan 10, 2016 · i := uint64(0xffffffffffffffff) i2 := int64(i) fmt.Println(i, i2) Output: 18446744073709551615 -1 Converting uint64 to int64 always succeeds: it doesn't change the memory representation just the type. What may confuse you is if you try to convert an untyped integer constant value to int64: i3 := int64(0xffffffffffffffff) // Compile time error!

What you are asking (to store 18,446,744,073,709,551,615 as an int64 value) is impossible. A unit64 stores positive integers and has 64 bits available to hold information. It can therefore store any positive integer between 0 and 18,446,744,073,709,551,615 (2^64-1).
