A class that adopts the decimal number behaviors protocol.


This class allows you to set the way an NSDecimalNumber object rounds off and handles errors, without having to create a custom class.

You can use an instance of this class as an argument to any of the NSDecimalNumber methods that end with ...Behavior:. If you don’t think you need special behavior, you probably don’t need this class—it is likely that NSDecimalNumber's default behavior will suit your needs.

For more information, see the NSDecimalNumberBehaviors protocol specification.


Creating a Decimal Number Handler

class var `default`: NSDecimalNumberHandler

Returns the default instance of NSDecimalNumberHandler.

Initializing a decimal number handler

init(roundingMode: NSDecimalNumber.RoundingMode, scale: Int16, raiseOnExactness: Bool, raiseOnOverflow: Bool, raiseOnUnderflow: Bool, raiseOnDivideByZero: Bool)

Returns an NSDecimalNumberHandler object initialized so it behaves as specified by the method’s arguments.
