How to print formatted Decimal value in Swift?

Question

How to print formatted Decimal value in Swift? NumberFormatter works only with NSNumber, but Decimal is a struct. String(format:) doesn't work either.

Answer 1

Decimal is bridged with NSDecimalNumber, which is a subclass of NSNumber so NSNumberFormatter can handle it

let decimal = Decimal(11.24)
let formatter = NumberFormatter()
formatter.numberStyle = .decimal
let string = formatter.string(from: decimal as NSDecimalNumber)!
