Question

I am trying to format some floats as follows:

1.1500 would be displayed as “$ 1.15”
1.1000 would be displayed as “$ 1.10”
1.0000 would be displayed as “$ 1.00”
1.4710 would be displayed as “$ 1.471”
1.4711 would be displayed as “$ 1.4711”

I tried with

NSString *answer = [NSString stringWithFormat:@"$ %.2f",myvalue];

Answer 1

I have figure out this. you can do this as per below implementation.

Please take a look at below demo code…

NSArray * numbers = [[NSArray alloc] initWithObjects:@"1.1500",@"1.1000",@"1.0000",@"1.4710",@"1.4711",nil];

for (int i=0; i<[numbers count]; i++) {
    NSArray * floatingPoint = [[numbers objectAtIndex:i] componentsSeparatedByString:@"."];
    NSString * lastObject = [[floatingPoint lastObject] stringByReplacingOccurrencesOfString:@"0" withString:@""];
    if ([lastObject length] < 2) {
        NSLog(@"%@",[NSString stringWithFormat:@"$ %.2f",[[numbers objectAtIndex:i] floatValue]]);
    } else {
        NSLog(@"%@",[NSString stringWithFormat:@"$ %g",[[numbers objectAtIndex:i] floatValue]]);
    }
}
