it doesn't matter if i can find the decimal representation for the given
bit pattern or not. the whole post is about removing the need to rely on
lossy binary->decimal->binary conversions.
Lossless turn-around is guaranteed if you are using sufficiently many
digits. In case of IEEE-754 single precision it's 8 significant decimal
digits.
it is highly platform-dependent. and both bin->dec, and dec->bin conversion
routines can contain errors, btw. so using decimal forms for exact
bit-patterns is the last thing i want to do, as i know how fragile they are.
