How do I remove decimal values from these numbers?

I'm making a Value that shows in a GUI. I'd like to know how to make the text say 1.34B when the player has 1345869475 "dollars", but it comes up as 1.345869475B. Can someone help me simplify this?

while wait() do
	Value = script.Parent.Parent.Parent.Parent.Parent.NPCNumber.Warrior.Value
	if Value < 1000000 then script.Parent.Text = Value
	else if Value >= 1000000 and Value < 1000000000 then script.Parent.Text = (Value/1000000).."M"
	else if Value >= 1000000000 and Value < 2147483647 then script.Parent.Text = (Value/1000000000).."B"
	else if Value == 2147483647 then script.Parent.Text = "MAX"
	end
	end
	end
	end
end

Any help is appreciated THANKS!
