Question

Okay so I’m trying to get my values rounded up to the nearest whole number with an IBAction.

So 1.88 -> 2.00 ,  
11.40 -> 12.00 ,   
111.01 -> 112.00, etc.    

–

-(IBAction)roundUp:(id)sender   
{   
    float floatRoundValue=lblTotalRound.text floatValue];
    ceilf(floatRoundValue);
    NSString *stringRoundValue = [NSString stringWithFormat:@"%1.0f", floatRoundValue];
    lblTotalRound.text=stringRoundValue;
}

That’s what I got. But it’s still rounding down below .5 and to the nearest integer

(Ex. 1.19 -> 1 , i need 1.19 -> 2.00). 

I’ve tried %1.2f but the value doesnt change at all.

What am I doing wrong?

Answer 1

ceilf is a function that returns a value (https://developer.apple.com/library/mac/#documentation/Darwin/Reference/Manpages/man3/ceil.3.html) , you simply need to change that line to the following.

floatRoundValue = ceilf(floatRoundValue);

So the complete code would in your case it would be something like this.

-(IBAction)roundUp:(id)sender   
{   
    float floatRoundValue=lblTotalRound.text floatValue];
    floatRoundValue = ceilf(floatRoundValue);
    NSString *stringRoundValue = [NSString stringWithFormat:@"%1.0f", floatRoundValue];
    lblTotalRound.text=stringRoundValue;
}
