I believe they should round-trip correctly, it's certainly possible to do
lossless base-2 to base-10 to base-2 round tripping. However, I've reported
a bug to one vendor (Intel/Linux, now fixed) when this didn't occur
correctly, so these kinds of problems certainly can occur :-(

I don't know what you can do about though, except point at the std lib
vendor responsible and say "blame them". :-(
