hi,
hey! you are using ruby. you can adopt nearly everything to your needs.

you could subclass  FXSlider and overwrite the methods so that they 
accept and return float values. something like this should work (note: 
untestet code without any errorchecking i.e. div by zero, 
@float_increment.nil? ...)

class Slider < FXSlider
def increment= increment
	super(1)
	@float_increment=increment	
end

def increment
	@float_increment
end

alias :old_value= :value=
alias :old_value :value

def value= set_value
	old_value=(set_value/@float_increment).to_i
end

def value
	oldvalue*@float_increment
end
end #class

others please correct me if i am wrong.
hope this helps,
