Decimal control in Labeled Display

Using labeled display i always get 3 decimals and no way to select how many to be displayed. Is there a way?

Thank you.

Can you show your code where you send the value?

if it is the same as mine, it is like this:

float roofHum;
Blynk.virtualWrite(V13, roofHum, "%");

if you take the , "%" away it goes back to like this:
