Subject [jira] [Commented] (MATH-1043) MathUtils.sum() method to add together a bunch of numbers.
Date Thu, 17 Oct 2013 20:28:47 GMT


Phil Steitz commented on MATH-1043:

I agree with Thomas on this.  Maybe we should play ping-pong indefinitely with this issue

More seriously, I can see how these could be useful little methods, but more [lang]-like than
[math]-like.  To get less flaky on why:

1.  lang's math features are easy convenience methods that don't do anything deep mathematically
but provide nice shorthand for common stuff (like pretty much everything else in lang).  So
this qualifies.
2.  I have sympathy but no burning desire and a little dread over extending all of the double[]-taking
methods in [math] to var args equivalents.  This has never been a demand from [math] users
and once we start down the path, we end up with quite a bit of new code to support.  

So basically, I am +0 to add this stuff to [lang], -0 to add it to [math]
