I'm seeing some strange bugs in my iPhone app that I have narrowed down to my use of NSNumberFormatter.
A stripped down example...
In Xcode playground I have:
let numberFormatter = NSNumberFormatter()
//numberFormatter.numberStyle = .DecimalStyle - does not change behavior
let numberString = "546000.06"
let number: NSNumber = numberFormatter.numberFromString(numberString)!
print("number: \(number)")
let number1: NSNumber = NSDecimalNumber(string: numberString)
print("number1: \(number1)")
This is the output:
number: 546000.0600000001
number1: 546000.06
Note that setting the numberStyle to .DecimalStyle doesn't change anything.
This issue only happens for certain numeric values (for example, 8.03 is another one). I thought NSNumberFormatter was safe for this type of conversion and I haven't seen much noise about this issue on the internet so I want to assume it is something I am doing wrong.
Can anyone explain what I am seeing? Any help is very much appreciated!
