Array object 16" o.c. with move to last

[joshua.harter]

Is there a way to create an array (to last) that has the consistent spacing of an array (to 2nd)?
I need an array that can populate between two equally spaced RP that will only fill in at a set increment, say 16" o.c.
I cant seem to figure out how to set the 16" so that the distance between the arrayed objects always comes out to be 16" while populating between two points.

SOLVED:

1. create a user driven length param: L
2. create a rounded length param to be applied to L, I called it 'L Array'
looks like this: L Array = round(L/16") * 16"
3. create a count param (integer) to drive the array, I called it 'Array Count'
looks like this: Array Count = (L Array/16") + 1

Now I have an array that populates incrementally at 16" o.c. along a length between two equally constrained ref planes.
Now I know its possible to use the round function to define whatever increments you want in length, not just for rounding fractional numbers.

One thing you want to do is to change your 'round' in step 2 to 'rounddown' this way the last object will never be beyond the L reference plane. If you do it this way you can then add an individual object that is locked to the L ref plane and then the last spacing will always be between 0" and 16"
