Thanks for all the feedback.

My problem was (of course) entirely my mistake.

I did not understand the difference between integer and Floating Point data type. An integer is just that, a whole number and so cannot get decimal places.

So trying to use %.2f format string with integer cant work. I Changed my DCIs to Floating point, and now %.2f for 2 decimal places is working fine.

Apologies to all.

I am sorry I was not clear.

The returned value for %s is, for example, 109.794250 plain and simple.

In the format string I have put %s kW so giving the result of 109.794250 kW

If I create a new DCI COntainer and leave the format string blank it returns: 109.794250
If I create a new DCI COntainer and put %s in the format string it returns: 109.794250

I can use any text around the %s such as Total Grid Power: %s kW which returns: Total Grid Power: 109.794250 kW

What I want to do is take the result from %s and reduce it to two decimal places.

So I don't think that its a string.

Best regards,

Alex

am I understood correctly that actual returned value contains floating point number and text "kW"? If yes, Java consider it as string and do not allow numeric formatting. You can change DCI data type to floating point number and use transformation script to remove unit indicator, like this:

if ($1 ~= "([0-9.]+) kW")
   return $1;
return $1;

Thanks for the response.

The DCI is a simple query an SNMP value (no transformations or anything) from a Schneider Powerlogic ION Power Meter, and the Map is a DCI Container, I have shown the raw value as well as some others with format string. I am aiming to get 2 deminal places precision.

I should add, that the DCI containers shown with data are using %s

Thanks,

Alex

could you post your DCI configuration and some actual values?

Best regards,
Victor
