compare two data

[supriyasenapati]

Hi I want to compare two numerics entered through numeric control a,b. If a=b then i want to see "RAM" , if ab then i want to see "JADU" in the indicator.in the front panel.I am using labView version 13. Please suggest Best Regards Supriyo Senapati

If they are integers, just use an equal comparison and a case structure. If they are floating point (e.g. DBL), all precautions of comparing floating point values apply.

Try something like this:

Thank you sir. I am trying it.

You could also simply use a select node and two string diagram constant.

Sir, my actual message did not posted clearly. I don't know why it happened. My actual message was like that -

I want to compare two numerics entered through numeric control a,b. If a=b then i want to see "RAM" , if a<b then i want to see "SHYAM" , if a>b then i want to see "JADU" in the indicator.in the front panel. I am using labView version 13.Thanks. Regards Supriyo

Check the concept on this link Nested Case Structure.

In another thread, Christian suggested something that I really think would apply here.  Subtract a and b and wire the result directly into a case structure selector terminal.  Set the first case to be "..-1".  This case will be for when a < b.  The next case will be "0" (for a = b) and finally "1.." for a > b.  Of course, this works best if using integers.  When using doubles, then you might want to be more careful.

Well, that's not that different. If this is giving you problems, you should probably start with some tutorials.

Try this:

 

This is cleaner than case structures, because a single image can show all code ;).

Most likely you pasted while in HTML Mode and stuff betweeen <> got stripped.

To reproduce, the  paragraph above was pasted below while the edit window was set to HTML, so that's clearly what happened!
