Question

I try to convert a string :

3033547640189791162

with this method :

NSNumber * myNumber = [NSNumber numberWithDouble:[tmpId doubleValue]];

and this :

NSNumberFormatter * f = [[NSNumberFormatter alloc] init];
[f setNumberStyle:NSNumberFormatterNoStyle];
NSNumber * myNumber = [f numberFromString:tmpId];
[f release];

and both of them give me this number :

<CFNumber 0x13a2b0 [0x3f54c9f8]>{value = +3033547640189791232.00000000000000000000, type = kCFNumberFloat64Type}

insted of :

<CFNumber 0x1b5550 [0x3f54c9f8]>{value = +3033547640189791232, type = kCFNumberSInt64Type}

Edit

When i try to use :

NSString *tmpId = @""3033547640189791162";

long i = [tmpId longLongValue];

i is equal to = -1631802438

int i = [tmpId intValue];

i is equal to = 2147483647

so i lose the original number value

Answer 1

Moving my comment to answer:

Try NSNumber * myNumber = [NSNumber numberWithLongLong:[tmpId longLongValue]];
