Hello,
What is your question exactly?
If it is about precision, then you should take in account that IPMI use
8-bit variables to represent values and some coefficients which
calculated based on MinValue/MaxValue parameters of corresponding
Sensor interface.
You will never get exact values in IPMI, unless you values can fit to
8-bit integer.
