String formatting: less decimals in %f float?

Question

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? — Voldemort, Dec 16 '12 at 21:42

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

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