iOS conversion to doubleValue doesn’t work .. but to integerValue does

[ulquiorra]

Hello all I'm trying to convert a string to a double and it doesn't work. However if I convert it to an integer it does work

this is my code snippet

int myDuration = [myDurationString integerValue];
int conversionMinute = myDuration / 60;

                        if( myDuration < 60 )
                        {
                                [appDelegate.rep1 addObject:[NSString stringWithFormat:@"%d",myDuration]];
                                NSLog(@"show numbers %d", myDuration);
                        }
                        else
                        {
                                [appDelegate.rep1 addObject:[NSString stringWithFormat:@"%d",conversionMinute]];
                                NSLog(@"show numbers %d", conversionMinute);
                        }

Now if I try to do

double myDuration = [myDurationString doubleValue];
double conversionMinute = myDuration / 60;

then it doesn't work. It gives me an output of 0.

So the integerconversion works but somehow the double doesn't does anybody have an idea why?

ps. I already tried changing the format specifier to %f ... still no succes.

double conversionMinute = myDuration / 60;

then it doesn't work. It gives me an output of 0.

Try:

double conversionMinute = myDuration / 60[COLOR="Red"].0[/COLOR];

Otherwise, you're dividing by an integer, which will cause a cast and be floored, resulting in a zero output in this case.

thanks for your reply , the problem though has already been solved.

It did some other stuff a elsewhere in my code that kind of messed it up a little thanks though
