[jira] Commented: (LANG-238) [lang] Add equals(type[]) to NumberUtils

    [ http://issues.apache.org/jira/browse/LANG-238?page=comments#action_12461598 ] 
            
Paul Benedict commented on LANG-238:
------------------------------------

I don't know if it is useful, but the float/double version could provide a precision field. Perhaps someone is interested if X values are equal only up to the Nth decimal point.

> It would be useful to add an equals() method like the current min and max
> methods which take an array type and determine if all the values are equal.
> I have found myself in need of this often. I have to retrieve objects from
> multiple data sources in parallel to build an array of complex object. To ensure
> validity, I always compare that my sub-retrievals returned the same number of
> objects as expected.
