For "storing or passing around" floating point values, you can keep
them *all* as binaries.

The problem is *computation*.
IEEE arithmetic is weird, but it is weird for good reason.

Admittedly JSON doesn't provide any official way to notate
±Infinity, but then JSON has very little in the way of semantics
for numbers anyway.  Someone wanting to send Infinity might well
send 1.0e400, and they'd be surprised and dismayed to get an
exception instead of an Infinity.
