How to round an float value and convert it into NSInteger value in the iPhone SDK?

Question

I need to round a float value and convert it into an NSInteger value.

For example:

float f = 90.909088;

I want the result to be 91. How to get rid of this?

Answer 1

A quick round and cast will work for negative values as well as positives:

NSInteger intValue = (NSInteger) roundf(f);
