I don't see why 10_000_000_000 could not be an **int** on a 64 bits platform and produce an error on a 32 bits platform. As there is always the possibility to write 10_000_000_000 'i64, this is not a restriction.
Furthermore, it would make things consistent as const c = 10 * 1_000_000_000 would give an **int** on a 64 bits machine and an error on a 32 bits machine (or, is it that it would give an **int64**? I don 't have a 32 bits machine to check this but it seems unlikely). But I will not fight about this point which is minor. As long as it is clearly stated that big literals are **int664** , I think I can live with that and use a conversion to get an **int** on 64 bits platforms . The real issue is this small inconsistency in the manual which deceived me.
