Objective-C Float Rounding
Use the C standard function family round(). roundf() for float, round() for double, and roundl() for long double. You can then cast the result to the integer type of your choice.

Original answer:
cast it to an int after adding 0.5.
So
NSLog (@"the rounded float is %i", (int) (f + 0.5));Edit: the way you asked for:
int rounded = (f + 0.5);NSLog (@"the rounded float is %i", rounded);
For round float to nearest integer use roundf()
roundf(3.2) // 3roundf(3.6) // 4You can also use ceil() function for always get upper value from float.
ceil(3.2) // 4ceil(3.6) // 4And for lowest value floor()
floorf(3.2) //3floorf(3.6) //3
