toNumber()
Converts the JavaScript value to a Nsnumber object.
Declaration
func toNumber() -> NSNumber!Return Value
A NSNumber object encapsulating the native representation of the value.
Discussion
If the value represents a Boolean value, the resulting NSNumber object is created as with the numberWithBool: method. Otherwise, this method uses JavaScript type coercion to convert the value to a JavaScript numeric value and creates a NSNumber object wrapping the result.
