Let us move to thread as this seems to cause quite a lot of clutter in global channel

Now you re calling sequence of `plus` on `1000` instead of a whole hours millis value This is because dot call ` ` takes precedence over multiplication <https kotlinlang org docs reference grammar html precedence> This works as expected for me ``` val millis Long = calendar get Calendar HOUR OF DAY toLong 60 60 1000 plus calendar get Calendar MINUTE toLong 60 1000 plus calendar get Calendar SECOND toLong 1000 plus calendar get Calendar MILLISECOND toLong val millis2 Long = calendar get Calendar HOUR OF DAY toLong 60 60 1000 + calendar get Calendar MINUTE toLong 60 1000 + calendar get Calendar SECOND toLong 1000 + calendar get Calendar MILLISECOND toLong Assert assertEquals millis millis2 ```

and the fact that it compiles and executes is very annoying what one would expect of this operation

dsavvinov · Answer

It certainly works as I ve demonstrated above Because users can override operators in general case one can expect anything from such operation e g such constructions make perfect sense for DSLs As I ve said for primitive types we could do better and report that expression is unused You can watch for updates on this ticket <https youtrack jetbrains com issue KT 12073>

Sorry if I sounded a bit harsh was frustrated after a whole day debugging a simple operation

It s a best practice to end multiline math operations with an operator so that you know that there is another line coming So I am ok with it working this way An IntelliJ warning on the line with the unused expression would be a welcome addition though
