digits of precision limit to 3 significant digits

[Susanne1709]

Hello!

I need 3 signifcant digits. If I choose 13 digits, it gives me 2 places. If I choose 14, it gives me all places. Can you please see the attached VI and help me? I need 3 decimal places. Is this possible?

Thanks 🙂

HI Susanne,

you need to choose a display format of "%.3f". Change the properties of the numeric control accordingly!

If you really insist on "3 significant numbers" you need to choose "%_3f", but all this is available in the control's properties dialog!

[Susanne1709]

Thanks Gerd.  The numeric properties of a control doesn't show "%_3f". Where can I find/choose it?

[GerdW]

In the control properties dialog!

In der deutschen Version ist das das "Anzeigeformat…", welches man entweder durch Zusammenklicken einstellt - oder über den "Fortgeschrittenen Bearbeitungsmodus"…

right click on the control, go to tab "Display Format"

@gerdw hatte extra geguggt, ob du schon geantwortet hattest 😉

[Susanne1709]

yes, I did that. and then?

btw: I don't have an control, it's an indicator but the properties looks the same 😕

Hi Susanne,

you surely don't want to "hide trailing zeros", don't need "automatic formatting" or 13 signifcant digits!

You wanted floats with 3 significant digits…

[Susanne1709]

while you were posting, I found it - thanks 🙂

has this changing consequences for further calculations?

every numeric indictaor, control, constant has this tab

this is AFAIK only representation, but i am not sure
