Function

NSDecimalMultiplyByPowerOf10(_:_:_:_:)

Multiplies a decimal by the specified power of 10.

Declaration

func NSDecimalMultiplyByPowerOf10(_ result: UnsafeMutablePointer<Decimal>, _ number: UnsafePointer<Decimal>, _ power: Int16, _ roundingMode: NSDecimalNumber.RoundingMode) -> NSDecimalNumber.CalculationError

Discussion

Multiplies number by power of 10 and stores the product, possibly rounded off according to roundingMode, in result.
