Discussion
Use the dot-notation form of this method when the call point allows the use of FloatingPointFormatStyle. You typically do this when calling the formatted methods of types that conform to BinaryFloatingPoint.
The following example creates an array of doubles, then uses formatted(_:) and the currency style provided by this method to format the doubles as US dollars:
let nums: [Double] = [100.01, 1000.02, 10000.03, 100000.04, 1000000.05]
let currencyNums = nums.map { $0.formatted(
.currency(code:"USD")) } // ["$100.01", "$1,000.02", "$10,000.03", "$100,000.04", "$1,000,000.05"]
