Convert NSNumber to NSDecimalNumber

I realize that NSDecimalNumber inherits from NSNumber.

However, I am struggling to figure out how I can init an NSDecimalNumber from an NSNumber or how to convert an NSNumber to an NSDecimalNumber.

I have tried

NSDecimalNumber* d = [aNumber copy];

where aNumber is an NSNumber object to no avail.

Am I missing something?

Thanks.

So: 

NSNumber * number = [NSNumber numberWithInt:10];
NSDecimalNumber *d = [NSDecimalNumber decimalNumberWithDecimal:[number decimalValue]];

And in Swift 

let number = NSNumber(int: 10)
let dec = NSDecimalNumber(decimal: number.decimalValue)

You can do:

NSDecimalNumber *decNum = [NSDecimalNumber decimalNumberWithDecimal:[aNumber decimalValue]];
