Maybe heavier than you'd like, but Protocol Buffers has a double type:
https://developers.google.com/protocol-buffers/docs/proto3#scalar
I recall reading of a hexadecimal serialization of floating point
numbers. I'm not sure of all the details, but it sounds like it would be
a fairly easy way to exactly represent a whole class of FP formats.

There are variations in the ieee 754 formats though, a

For VAX, you would need to do some work there, since it natively uses a
different floating point format. It is the canonical example for that,
these days :-) I'm not up to date on w
A bit of a random question/thought - what is a good and portable method
of storing/transmitting binary floating point numbers? Anyone aware of
any conversion functions in NetBSD that I can look at?
Searching the Internet, there are various opinions and references on how
to do it, but there doesn't
