Question

So, i was looking over some earlier code and found this random plus sign that should have been a syntax error, but the code worked fine and i don’t get why

tv_distance.setText("Distance: " + 
        ( dist >= 1000 ? (String.format("%.1f", dist/1000f)) : +dist )
        + " " + metric );

The extra plus sign is at the third operand of the ternary operator:

() ? () : +dist

So what am i missing?

Answer 1

dist is a number. The + is just specifying the sign. For example, +5 is always the same as 5 but it is legal. Obviously, you’re much more familiar with its opposite, as in -5.
