Wouldn't that only be possible if the processor reports if an IEEE
floating-point conversion / operation was inprecise / innacurate (can't
for the heck of it remember which term applies here.)

Even if that was the case, that means that say a floating point division
would take would take one attempt, report that, convert the floating
point numbers to BigDecimals, and then perform the division in Ruby.
This isn't something I'd like happening in code even casually working
with floating point numbers for performance reasons. Though it's a valid
Shiny Thing to put as an optional mode of operation.
