Show the float value in formatted string two digits after decimal in iPhone

Question

I have a float number in which i insert comma after thousands value it works fine

NSNumberFormatter *formatter = [NSNumberFormatter new];
[formatter setNumberStyle:NSNumberFormatterDecimalStyle]; // this line is important!

NSString *formatted = [formatter stringFromNumber:[NSNumber numberWithFloat:appDelegate.C_WND_ClinInf_Average_Default]];

but it shows 1,947 but i want it to show 1,947.00 any idea how to formate like this.

Thanks

Answer 1

Have you tried using -setMaximumFractionDigits from NSNumberFormatter?

So, try something like:

[formatter setMaximumFractionDigits:2];
[formatter setMinimumFractionDigits:2];

This way you deal with NSNumberFormatter only and don't need to call anything extra on NSString.

Answer 2

简单写

NSString *myNum = [NSString stringWithFormat:@"%.2f", yourFlotNumber];

Answer 3

try this one its work fine for me...

---

NSNumberFormatter *formatter = [NSNumberFormatter new];

[formatter setPositiveFormat:@",##,###.00"];
NSString *formatted = [formatter stringFromNumber:[NSNumber numberWithFloat:no]];

Answer 4

    NSNumberFormatter *formatter = [NSNumberFormatter new];
        [formatter setNumberStyle:NSNumberFormatterDecimalStyle]; // this line is important!

        NSString *formatted = [formatter stringFromNumber:[NSNumber numberWithFloat:appDelegate.C_WND_ClinInf_Average_Default]];


  NSString *str = [[NSString alloc] initWithFormat:@"%.2f",yourfloatno];

try this one .....

Answer 5

I would rewrite your code a bit...I don't think you need a number formatter.

float myNumber = appDelegate.C_WND_ClinInf_Average_Default;
NSString *myNumberAsText = [NSString stringWithFormat:@"%.2f",myNumber];

Hope this helps.
