How do I achieve the following conversion from double to a string:
1.4324 => "1.43"
9.4000 => "9.4"
43.000 => "43"
i.e. I want to round to to decimal places but dont want any trailing zeros, ie i dont want
9.4 => "9.40" (wrong)
43.000 => "43.00" (wrong)
So this code which I have now doesn’t work as it displays excess zeros:
[NSString stringWithFormat: @"%.2f", total]
Use NSNumberFormatter. See the Data Formatting Programming Guide‘s chapter on Number Formatters.
