isEqual(to:)
Returns a Boolean value that indicates whether the number object’s value and a given number are equal.
Declaration
func isEqual(to number: NSNumber) -> BoolParameters
- number:
The number to compare to the number object’s value.
Return Value
true if the number object’s value and number are equal, otherwise false.
Discussion
Two NSNumber objects are considered equal if they have the same id values or if they have equivalent values (as determined by the compare(_:) method).
This method is more efficient than compare(_:) if you know the two objects are numbers.
