Function point scale is a function set for displaying decimal points in numerical function points. The reported value is 1, and setting the multiplier to 1 means that one decimal place is 0.1. Setting it to 2 means that two decimal places are 0.01. For example, if you want to display the temperature function point 36.5 ℃ in the device panel, you need to set the function point multiplier to 1. When the device reports 365, the panel will display 36.5.
