Objective-c: How to round off Float values? [duplicate]

Answer 1

The function lroundf() will do it:

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

Answer 2

Convert to int and then convert back to float.

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

This will work

Answer 3

In addition to the 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 decimals, see the question mentioned by Alex Kazaev.
