I want to convert a number (with a comma separating 1000s) such as 1,220 to a decimal. Without the comma I am just doing
[numberString doubleValue]
Is there a simple NSNumberFormater to have it recognize the comma as part of the number and not a "character" so the answer I get is 1220?
I used this:
myNewString = [myNewString stringByReplacingOccurrencesOfString:@"," withString:@""];
quote = [myNewString doubleValue];
Is this the best way? Is there another cleaner method?
There is a way without Formatter
let num = "1,220"
let strippedNum = num.replacingOccurrences(of: ",", with: "")
let val = Double(strippedNum)with formatter, you have to use numberStyle
let formatter = NumberFormatter()
formatter.numberStyle = NumberFormatter.Style.decimal
formatter.locale = Locale(identifier: "en_US") // not needed if current is en_US
let val2 = formatter.number(from: num)I think your approach is quite logical and optimal. Treat a string "1,210" like a string and delete the offending "," character as you would delete any character in a string. If you want to reinsert a character in a number then use an NSNumberFormatter.
The value of Formatter vs "brut force change" is to better localize.
