how to save a float to nsnumber with just two decimals

Question

I'm trying to save a float to an nsnumber but i just want to save it with two decimal places. I know I can do it by converting to an NSString first using this code

NSString* formattedNumber = [NSString stringWithFormat:@"%.02f", myFloat];

but seems clumsy. All I want to do is convert

float numb = 23.25454 into NSNumber 23.25

Answer 1

Use this

float numb = 23.25454;

NSNumber *num = @((int)(numb*100)/100.0);

Answer 2

Just round it using any of these functions

float rounded = round(val * 100) / 100;
float rounded_down = floorf(val * 100) / 100;
float nearest = floorf(val * 100 + 0.5) / 100;
float rounded_up = ceilf(val * 100) / 100;
