Right, the manual could be updated, I guess. The last one, gives you Int32 on 32-bit platforms. This i all intentional. Then there is Int128 and BigInt (no modular there). > > These last 3 results seem inconsistent (and the manual incorrect) > because for example, typeof(typemax(Int8)) -> Int8 and not Int64, so no, > Julia doesn't do modular arithmetics all the time. > > -- > Resistance is futile.
