Why, when there is a division by zero, the color changes? How can I revert to the previous behavior?

[bonomani]

This was a breaking change over original version: Division by zero is an error !

As division by zero is an "exception" and should be treated as such.
When a division by zero occurs the value is now set to NaN ans the color is set "blue" -> This mean the test is "disabled" (as we usually not test anything. There are some objections doing so, but it's the current implementation: let me kown if you thing this should change!)

Is it normal? or is it a alarm? or something in between?

In some case it is normal: web can use the "thresholds" file to treat this case as you want:
These are usually 3 possibilities that you can use to change the color:

1. You can let it as it is.

2. You can change the color to "No report" : example
   ifInErrPct : clear : NaN :
   ifOutErrPct : clear : NaN :

3. You can make it as "Normal": example
   ifInErrPct : green : NaN :
   ifOutErrPct : green : NaN :

But of cours you can put the color you want! (i prefer the "clear" one!Error handling will probably be redesigned because it's not really satisfying
