[ant_inter]

and i wanna delete some values after "0,0".

Im working with LV 7.0

Any help will be sincerely appreciated.

Thanks.

What have you tried so far?

Are those zeroes real data or just markers?

Your problem has 2 components. First, you need to find the zeroes. Search 1-D Array might work for you except that with floats you're going to want to use an In Range search.

Deletion is pretty straightforward using the Delete from Array function.

You'll probably want to do this in a loop with shift registers.

Those zereos are real data.

For now I tried with function "In Range and Coerce".

Tnx

Do you also want to delete the zeroes themselves?

In your example, what would the desired output array look like?

Comparing your title and your text, it seems that some=five. Is this correct?

ISo the zeroes are "real data", are they true zeroes or could they also be very small numbers very close to zero?

[ant_inter]

Hi,

No, i wanna keep the zeroes. They are true zeroes.

Comparing your title and your text, it seems that some=five. Is this correct?  Five or more than five.

My array someday will look like this:

Have: 51,9	Wanna have: 51,9
51,9	51,9
51,9	51,9
0,0	0,0
0,0	0,0
0,0	0,0
200,0	0,0
172,2	0,0
158,4	0,0
52,4	0,0
51,7	0,0
51,3	51,3
51,1	51,1
51,0	51,0
51,0	51,0
0,0	0,0
0,0	0,0
0,0	0,0
0,0	0,0
0,0	0,0
51,3	0,0
51,4	0,0
51,4	0,0
51,5	0,0
51,7	0,0
51,7	51,7
51,8	51,8
51,9	51,9

I wanna delete five or more values in array after last zereo value.

Tnx

OK, so you don't want to delete them, but replace them by zeroes, keeping the array szie the same. that a big difference and actually makes thing simpler. What have you tried?

Computers need clearer instructions, so the "or more" is ambiguous. How is the program supposed to know how many. Is the actual number an input to the program?

Hi.

I appologize for bad explanation.

>> OK, so you don't want to delete them, but replace them by zeroes, keeping the array szie the same. <<

Yes I wanna replace them with zereos and keep array in same size.

For now I didnt do nothing useful. Im workink with "Search 1D Array" and with  "Replace Array Subset" functions.

Yes. Number is input (control)  to the program.

Thanks again

As long as they are true 0, use Search 1D Array to find the first 0.  From there check each item and compare it to 0.  If it is 0, go to the next.  If it is not 0, then use Replace Array Subset with that index.  For the values to replace with, use Initialize Array with 0 as the value and your input number as the array size.

Try something like this (should be sufficient unless the arrays are gigantic).:

 

(false case is simply wired across)
