B4i Library [class] DecimalNumber (similar to B4A BigNumber)

This class uses NativeObject to access NSDecimalNumber type. Unlike BigNumber library, the objects are immutable. This means that the value of a DecimalNumber instance cannot change. A new value can be assigned.

Usage example:
B4X:
Dim dm1 As DecimalNumber = CreateDecimal("123.11111111111111111111")
Log(dm1.Add(CreateDecimal("0.22222222222222222222")).ToString)
Log(CreateDecimal(2).Multiply(CreateDecimal(10)).ToString)
Log(CreateDecimal(100).Divide(CreateDecimal(10)).Subtract(CreateDecimal(5)).ToString)

Sub CreateDecimal(Value As String) As DecimalNumber
   Dim dm As DecimalNumber
   dm.Initialize(Value)
   Return dm
End Sub
