Simple Case question

[Tom]

I know how to do simple case structures ie True and False. Suppose
however I have an integer N and I have three possibilities:

Case1

if N>5
it does one thing
case 2

if N<-5
it does something else
case 3

if -5<5
it does a third thing.

How to do this in the simplest way?

Thanks

Tom

Hi Tom,

Attached is a V7.0 example of a simple solution to your problem.

Hope this helps,

Nick

Hi,

You can click in the white box where it says "TRUE", while the I cursor is
selected (with tab).

In this box you can now put "1,2,3", "5..", "..5", etc. If there is a number
missing (e.g. two cases : "..5", "8.."), you'll have to make a default case.

The case always selects including the number (floating point numbers are
converted to integer). So in you example you need :Case 1: "6..", Case 2:
"..-6", Case 3: "-5..5". This does not exactly what you want but: "N>5",
"N<-5", "-5=
Regards,

Wiebe.

In at least LabVIEW 6.0 and later:


Case1 selector value = "6.."
Case2 selector value = "..-6"
Case3 selector value = "-5..5"
(dont input the ")
This is for integer values.

If you have floats then you will need to use a rounding function and
convert the number to integer afterwards. To get exactly the case values
with floats will need some work. If this is the case and you have a problem
with that then post again.

Out of many solutions....
Hope this quick example helps!

Don`t forget, that if N=5 or N=-5, you will have a fourth case.....

>= and <= are required somewhere I would guess.

Thanks you that seems to work but how do I input the integer values
into the case from the front panel? ie how do I make a control such
that I can vary
the limit 5 to 6 or 7 or whatever from the front panel?

Thanks

In this case, you need to use three cases with boolean logic.

In this example, the function checking if the supplied number is in range can be right-clicked to change whether the limiting values themselves are considered valid or not (Including maximal or minimal / excluding maximal or minimal).
