Looking up an authoritative source (ie.: "the docs") is one way. Here is what I found: https://tour.golang.org/basics/11 The int, uint, and uintptr types are usually 32 bits wide on 32-bit systems and 64 bits wide on 64-bit systems. When you need an integer value you should use int unless you have a specific reason to use a sized or unsigned integer type. Another would be to try to do an operation that would wrap around, but if you aren't familiar with binary arithmetic in the language in question, just looking it up is probably easier.
