Does a value of 0 make any sense? etc. The value displayed to the user must make some sense or explained with context. In this case, perhaps a percentage would work, with the default value being "100%", and the max and min values displaying 50% and 200%, or something, or whatever the scale actually is.

  With percentage there's no need to set a slider in my opinion. It's intuitive that 0 and 100 and the limits. That implementation would be good with the real values libinput handles for "AccelSpeed" option, showing the slider moves between -1 and 1, see here <https://www.mankier.com/4/libinput>.
  
  But if that case @ngraham will say the ticks are too many for the slider and we lose accuracy. There's no way to build a slider like the brightness one (plus a spinbox) inside power management kcm with real values and without ticks? A format function to round on at least two decimal will be given.
