I have a float value, that I would like to show it in format string and if it corresponds to an int, showing the integer, if not, showing it with one decimal.

Like this :

3.1
3
2.9
2.8

For now I’m stuck, in the concept, I’d do something like that :

float myFloat = 3.1
float mySecondFloat = 3
[NSString stringWithFormat:@"%g %g", myFloat, mySecondFloat];

My question is:

1/ the type format “%g” works in most cases but sometimes i have result shown like “0.600001” while in reality there should be 0.6 because all I do is 0.7 – 0.1.

Is there a kind of type cast for float at 1 decimal or maybe a bitwise operation to get rid of the final imprecision, or other way to make it works in 100% of cases ?

Thanks for your answers.
