Objective C: Formatting numbers with "just enough" decimal places

Question

Is there a quick way to format numbers (e.g., when using appendFormat) so that only enough decimal places are shown? E.g., 4.23100 is shown as 4.231, while 5.0000 is shown as just 5.

Thanks for reading.

Answer 1

Use %g instead of %f

double n = 1234.5678;

NSString str = [NSString stringWithFormat:@"number is %g", n];
