		return CalculatedDecimalProperty(() => 
			Operation.EditItem.Number.Nvl()); 
	}
}

Explanation of the example

The example above works as follows.

• Line 1 defines a ReadOnlyDecimalProperty with the name DecimalNvlExample.
• In Line 5 and 6 the content of this property is going to be calculated and assigned.
• In line 6, the Decimal Operation.EditItem.Number is evaluated, by adding .Nvl.
• If the Decimal appears to be NULL, then DecimalNvlExample will be assigned the value after �Nvl between parentheses. When nothing is specified, the default value will be zero (0)�.
