More accurate setting for the temperature coefficient

I use a Takahashi FSQ 106N with the original rack & pinion focuser that has no reduction gear. With the Robofocus motor (3600 steps/revolution), which is adapted directly to the focuser shaft, 1 step corresponds to 6,67 µm. The scope has a temperature coefficient of about 50 µm/K which corresponds to only 7,5 steps/K. However, until now, the temperature coefficient can only be inputted as an integer. This results in relative large deviations when the temperature difference becomes huge.

For that reason I need a more accurate setting for the temperature coefficient in SGP. The input should have at least 1 decimal place. Please be so kind and modify the input box and number format.
