[Chicken-users] thoughts on alternate "posits" / "unums" instead of traditional floats?

[Daniel Ortmann]

I am probably the last to run across this alternate floating point
format ... but now I am curious.

If these posits were implemented in Chicken, what sort of work would be
required?
Would they replace the traditional floats?
Or would they be an optional part of the numeric stack?

Just curious.
