That seems to be more a problem of strings that of floats, then.

Strings have nothing to do with the issue that there is no widespread lossless text exchange format for FP. Instead we round FP numbers while encoding (like "0.3") and then "deround" it while decoding.

(Lossless base10 encoding of 0.3 single precision would be like "10066330*2^-25"..not very readable).

If you have to use strings as the intermediate representation (why?) Then printf("%x") and scanf("%x") is perfectly lossless and widespread.

The only thing that's lossy is converting floats to decimal point numbers, which is absolutely silly if it's just two machines communicating.
