im trying to functionaly save a longe range sonar thing but it just resets to 0 or 1 after loading it, is there any way to make this tiny 0.1-0.76 tempuratures without it rounding up or down?
Nope. Temperatures save as integers. (Except I think in the range [roomtemp-128, roomtemp+128) in which they still save as integers with a bias of roomtemp = 295.15, so the temperatures in those ranges are integers on the celsius scale.)
