Thanks for the proposal. I don't have much of an opinion on this and right now I am mainly wondering whether there is prior art which can inform us that this is relatively widely useful? Base-2 (bit) rounding is implemented in Numcodecs <https://numcodecs.readthedocs.io/en/stable/bitround.html#module-numcodecs.bitround> in the context of data compression. As pointed out by M. Klöwer et al. in <https://doi.org/10.1038/s43588-021-00156-2> "Rounding bits without real information to zero facilitates lossless compression algorithms and encodes the uncertainty within the data itself." I'm not an expert, but I never encountered rounding floating point numbers in bases different from 2 and 10. Stefano
