In Objective-c How to round Float values?

Answer 1

In addition to other answers:

float theFloat = 1.23456; int rounded = roundf(theFloat); NSLog(@"%d",rounded); int roundedUp = ceil(theFloat); NSLog(@"%d",roundedUp); int roundedDown = floor(theFloat); NSLog(@"%d",roundedDown); // Note: int can be replaced by float 

For rounding to specific decimal places, see the question mentioned by Alex Kazaev.

Answer 2

The lroundf() function will do this:

 float a=20.49; int myInt = lroundf(a); 

Answer 3

Convert to int and then convert back to float.

 CGFloat *myFloat = 100.765; NSInteger *myInteger = myFloat; CGFloat *newFloat = myInteger; 

It will work
