Well, I am using %f for displaying float values in my string. However, the values are too accurate (around 6 decimal digits after the point). I'd like to only display 1 decimal. But how?

    Was there even an *attempt* to find some documentation first? –  Sep 10 '11 at 01:42

  • @pst: No, there wasn't any attempt as far as I can recall. Why? – Saturn Dec 16 '12 at 21:42

%0.2f or some other number after the decimal point.

NSLog(@"%0.1f", floatThing);

I think that should work. For more decimals change 0.1 to 0.2, 0.3, 0.4 ... etc.
