1) Give a description of the problem
The routine is to assign average temperatures into a variable
2) What is the expected behaviour?
It is doing what it is supposed to do
3) What is happening/not happening?
It is providing an average of up 12 decimal places, I want to limit it to two places
**4) Post a Green Snapshot of the piston![image|45x37]
You can use the round function to limit decimal places…round(number, # of decimal places)
Personal preference, I would set a local variable first, round it, then set the global variable
Set variable AvgTemp1 = Average of Device 1, Device 2…
Set variable AvgTemp1 = round(AvgTemp1, 2)
Set variable @@AvgTemp1 = AvgTemp1
Agreed, the problem I have is it is not allowing me to:
Set variable AvgTemp1 = round(AvgTemp1, 2)
I have tried all Value choices and none put the value of the variable in the argument statement.
Also,
Set variable @@AvgTemp1 = AvgTemp1
Will not allow me to enter AvgTemp1 as the variable to derive value from.
I did define AvgTemp1 as a dynamic variable
What am I missing?
AvgTemp1 should be a decimal variable
Initially set just like before for average of each device temp…
The round function has to go into the expression field
Awesome, there are ways to make it look a little cleaner if you are interested.
Something I like to do is create a device list variable so that if you ever want to add or remove devices you just change the one variable; this is a simple use case so probably not a big deal but helpful if you are referring to the same device list multiple times in a piston.
When I was coding for a living I did the same – creating a variable table. Of course, you should always go back and tighten the code
TBH this is the first time I have needed to create a variable in WebCore
