Temperature is rounded #18

Hi there,

thanks for your work! The k10temp module provides me more detailed temperatures, so it seems to me this module round the values?

Hi, there is no rounding of the temperature within the driver, the temperature values read from the ASUS WMI do not have any decimal places.

I am unsure if this is a limitation of the IT8665E or if it's done within the ASUS firmware, but there isn't anything I can do to add more precision, sorry!

There are no decimal places shown within the UEFI, or in HWiNFO for the same IT8665E derived readings:
