I'm not sure what you mean by "arbitrary place values" with Bitcoin; if you are implying it's infinitely divisible, it isn't. You'd do the same trick with Bitcoin: represent it as an integer¹. The value 1 is 1 sat, or 0.00000001 BTC. ¹(where you need to; otherwise, I'd use some fixed point type if my language supports it)
