When the threat level is set in the Chemical Detector and more then 2 decimal places are used, then in many cases the 2. decimal places is omitted.
I would expect that a threat level that has too many decimal places would be rounded properly to the 2 decimal places.
Threat Level is set as described here https://community.bistudio.com/wiki/Arma_3_CBRN
_obj ctrlAnimateModel ["Threat_Level_Source", _x] leads to following values shown in the Chemical Detector
0.921 -> 0.92
0.922 -> 0.92
0.923 > 0.9
However
0.821 -> 0.82
0.822 -> 0.8
0.823 -> 0.8
