xCode Round float

Question

i have number:

3.08

and i use this:

NSLog(@"%1.1f", self.test.value);

but console output 3.1 not 3.0 i need output 3.0 pls help...

Answer 1

That is because it is rounding up. This might work to force it to round down:

NSLog(@"%1.1f", floor(self.test.value*10f) / 10f);
