Format number as percent

I have written this code and I want to format the number z as percent.

float l = ([textField2.text floatValue]);
float g = ([textField1.text floatValue]);

float x = l/1.23;
float y = x-g;
float z = y/l;

label.text = [[NSString alloc] initWithFormat:@"%2.2f \%",z];

NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setNumberStyle:NSNumberFormatterPercentStyle];

[numberFormatter setMinimumFractionDigits:2];  //optional
....

NSNumber *number = [NSNumber numberWithFloat:0.435];

NSLog(@"%@", [numberFormatter stringFromNumber:number] );

43,50 %

Make your code as follows.

label.text = [[NSString alloc] initWithFormat:@"%2.2f %%",(z*100)];

You need to use %% in order to print a percent sign in a format string.
