numeric input

[kzeng]

I'm completely new to labVIEW and I was wondering if there was a block in the block diagram that had an input and output.  I'm trying to do some conversion by multiplying an input from the front panel by a numeric constant and then storing that multiplied value into a variable.  I tried using a numeric constant, but that only has an output so I can't store the value into that constant.  Is there a block that I'm missing or what?

You really need to start with some of the free tutorials. The function that you are missing is the multiply it seems. That's about as basic as you can get.

And what is this variable used for?  Data for the next iteration?  If so, use a shift register.  Otherwise, wire the output to whoever needs it.  But it is really hard to give any real advice without some really good contex.

Nope nothing is missing.  The block diagram is like the source code (sorta).  So imagine you are in a texted based language.  You just asked if there is a way to display the result of some calculation...in the text source after the application runs.  Well sorta but you'd never want to do that.  You'd want a UI element to display the value in.  So make an indicator on the front panel.  Here is some free training if you want to know more.

Yes, most all have both inputs and outputs. 🙂
