If a jet engine is bolted to the equator, does the Earth speed up? Anyway, in Arduino, byte, uint8_t and unsigned short can be used interchangeably because they are literally the same type. Numeric literals cannot have short or unsigned short type.. Of course in order to assign to bar, the value of the literal is implicitly converted to unsigned short.In your first sample code, you could make that conversion explicit with a cast, but I think it's pretty obvious already what conversion will take place. (Technically I believe you can pass an int in place of unsigned if the value is positive, since the representations are required to be the same, but here the int you're passing (the promoted value of sNum) is negative.
