Converting NSDecimalNumber to NSDecimal

I am using the CorePlot library to generate some charts. While I am working on this, I have come to the need to change the X-axis property Xaxis.MajorIntervalLength

, which is NSDecimal.

I tried, but I cannot create the number NSDecimal

. I can only create NSDecimalNumber

and when I try to assign it to a property it throws this error:

Assigning to NSDecimal from incompatible type NSDecimalNumber

      

        
        
        
      

    

I know NSdecimal is no longer an Objective-C class, but I guess, but I need to use it somehow!
