Converting floats to a String with commas

[roeik]

What's the best way to convert a any number to a string with commas?
so for instance:

int i = 1000000

will be printed as 1,000,000

thanks

Look for stringWithFormat.

[roeik]

I did, but I can't find a comma notation there, only scientific notation.

Since i use it seldom I cannot give you the entire info.
But the following is outside from one of my running programs.
The documentation under XCode Help is very good, as far as I remember.


[NSString localizedStringWithFormat:@"%1.1f%%", [[NSNumber numberWithFloat: 1011.213 ]

Look at NSNumberFormatter.

[roeik]

Just for other people who needs it, the specific command is:
[numberFormatter setFormat:@"$#,##0.00"];

(I added the $ sign to add the currency symbol).

for some reason when running the app on the device you get an error message when using setFormat.
Instead use:

numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
[numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
