How to add a Kill Death Ratio to a DataStore?

I'm a bit confused on how exactly I would do this. I have the rest of my DataStore fully functioning, but this is the only part I'm not so sure about.

	local KDR = Instance.new("NumberValue", StatNumbers)
	KDR.Name = "KDR"
	if Kills.Value == 0 and Deaths.Value == 0 then
		KDR.Value = 0
	elseif Kills.Value >= 0 and Deaths.Value > 0 then
		KDR.Value = Kills.Value/Deaths.Value
	elseif Kills.Value > 0 and Deaths.Value == 0 then
		KDR.Value = Kills.Value
	end

When I go to view my stats and the output, I get this number: -2147483648 I have my Kills set to 28 whilst my deaths are set to 3, so I was expecting a number around 9.3. What should I change to fix this?

You don't need to divide the kills by 0, so just put the kills.

local KDR = Instance.new("NumberValue", StatNumbers) 

KDR.Name = "KDR"
if Kills.Value == 0 and Deaths.Value == 0 then
	KDR.Value = 0
elseif Deaths.Value > 0 then
	KDR.Value = Kills.Value/Deaths.Value
else
	KDR.Value = Kills.Value
end
