I'm looking to do some adding. For one, I'd like to be able to quickly add the numbers present in a list together. No [zl] mode that I know of does this. My list contains, for example, [1, 3, 4, 6, 7]. Upon inputting the list into this object, the sum (21) will be output.

Also, I'd like to have an object or abstraction that keeps a running total of the sum of all the numbers which are input into it.

These two are actually pretty similar. What's the best way of accomplishing this in 4.6?

but bizarrely on my machine on both max 5 and 4.6, accum isn't accumulating.

Thanks for the responses. I'm not familiar with [accum]. Sounds like I need to get familiar.

There is a zl mode. It's zl sum. I'm not sure if that mode exists under 4.6, however. Accum certainly will work, and you could easily use iter, trigger, and accum together to make an abstraction that did the same thing as zl sum.

another option, providing the lists don't get longer than 9 items:

expr $i1+$i2+$i3+$i4+$i5+$i6+$i7+$i8+$i9

Lp.sigma is in the Litter Starter Pack. URI below.

Some folks have suggested that a name like "lp.add" or "lp.sum" might be more obvious, but I actually polled Litter Power users on this and the broad majority found sigma sufficiently obvious and/or more attractive. So there it is.

Cute, but does have potential precision problems with int/float conversion.

Never mind that it's a Rube Goldberg-like solution to a simple problem. (Heath Robinson for the Brits)
