That would be an interesting experiment indeed. Either use one of the IEEE754 decimal float formats (https://en.wikipedia.org/wiki/Decimal_floating_point), or Douglas Crockford's DEC64 proposal (https://www.crockford.com/dec64.html, which strangely enough does not refer to the older IEEE standard). There are implementations of both for various other languages that can serve as inspiration. Konrad.
