In my case, I tried:

tmini = 0
tmaxi = 60
CorF = C

cpuRawTemp = 56900

Line	Variable	Formula	Actual	Expected
141	value_a	100/(tmaxi-tmini)	1	1.667
142	value_b	-value_a*tmini	0	0
146	cpuTemp	cpuRawTemp/1000	56	56.900
154	value	cpuTemp	56	56.900
157	fanPercent	value_a*value+value_b	56	94.852

We will need to multiply the values by 100, perform the operations then divide by 100. I don't have time to do this now.

@mxr can you handle this? It's related to the way bash handles fp. It's truncated at the point.

I don't use this addon anymore (no longer using this hardware). Not sure if bc is available but you could also try something like

value_a=$(bc <<< "scale=3; 100 / ($tmaxi - $tmini)")
value_b=$(bc <<< "scale=3; -$value_a*$tmini")
