convert scalar to boolean

[Basa]

Hi.
I have created an array which contains 13 elements. These elements are scalars (double, 64 bit real) with the values 0 and 1. The array is initialised with 0s and the number of 1s is defined by user input. The VI is attached.
I want to extract each single scalar from the array and afterwards convert them to boolean variables. How can I achive this?
Thanks for help.

To extract elements from an array, you can use the Index Array function or an auto-indexed for loop. To convert 0 or 1 to a boolean simply use the Not Equal to Zero VI from the comparison pallette - if the number is 0 you'll get an F and if it isn't you'll get a T. However, the nice thing about LabVIEW is that you can often perform the same actions on different types of things. In this case you can wire the array directly into the Not Equal to Zero VI and you'll get an array of booleans - each corresponding to an element in the original array. Here's an example that shows all three.

Thanks for your quick answer. Meanwhile I was able to solve the problem. Did it similar to your suggestion. My problem was that I didn't think of the comparison palette which offers simple solutions to my question. My fault. ;o)
Anyway thanks for help!

The other thing to be careful about is that the binary and decimal representations of numbers can produce results which may not be what you expect. When doing comparisons on non-integer numbers it is safer to compare to a range rather than comparing equality. If your ones and zeros are the result of a calculation, a zero might be 1.2838453-82 and a one might be 0.999999999999999... Comparing to 0 or 1 will give a Not Equal result. The In Range and Coerce function is useful in cases like this. Another approach is to compare to a threshold between the values. If x > 0.5 then true, else false.
