Which is more effiecient on cFP 2020

[Grub]

Which method of delivering a true or false  to a set of boolean indicators from a numeric array is more efficient:

1.  COnvert the numeric elements into an array of booleans with a for loop and a 'replace array subset' function.  Then convert the array into a cluster, unbundle the cluster an deliver the true or falses.

2. Convert the array into a cluster, unbundle the cluster into individula numerics and then convert them into booleans.

Thanks,

Sorry, but I cut out the middle man here and figured it out myself....

As it turns out, I couldn't even find an ' integer to boolean' conversion function.  I ended initializing the original array as a set of booleans.  I still haven't gotten to use a for loop yet in my VI....!!! 

Still, I would like to know the answer to my original question.

There is a number to boolean array function (Boolean->Boolean Array to Number/Number to Boolean Array).  Just index the boolean array to obtain whichever elements you need.  Note that the least significant bit is the leftmost (or topmost - depending on how you resize it) in the array (on the front panel), or the 0th element in the array.

I'm sorry I don't know the answer to your original question though.

Hello!

Here a small example which operates with separate booleans without loop. You can use polymorphic VIs.

It seems to me, metod efficiency depends on boolean representation, array size, numeric-to-boolean conversion algorithm.

anything is IMHO
