labview floating point and decimal differentiation

[tan99323]

Hi, Can i know what modification can I make to let the display differentiate between floating point and decimal. For example, when I input 2+2. I would like the output of 4 instead of 4.000. And when the input is 2.2 + 2.2, how to get the output of 4.4 instead of 4.4000. And also would like to have keep 4 decimal for trigonometry function.

Hi tan,

set the display format of your indicator to "hide trailing zeros"…

Spoiler

Something like %#.4g would help…

But the indicator in the VI is string type. There is no option to set hiding trailing zero for that string indicator.

In this case you are doing the NumToString conversion before displaying the result in an indicator.

Use FormatIntoString with the format string I mentioned in the other message…

(Now it would help to provide your VIs for older LabVIEW versions like my LV2017.)

In case to enable insert numpad input while the VI is running, what modification can I make ? So user can input date from numpad instead of press those boolean button.

You need to catch those keypress events…

(Btw. you should use the ValueChange instead of MouseDown events.)

I have tried to change the event for 0-9 to value change , but still unable to input from keypad. Which element should i add to the VI ?

Hi tan,

you need to look for keypress events...

[tan99323]

So, I need to duplicate the 0-9 mousedown event and change to key down on the new duplicated event ?

Hi tan,

no need to duplicate anything.

Just catch keydown events of your VI…
