  • One of the linked papers makes the claim that the circuitry would be less complex than that needed for floats, but also includes this note:

    Floats have one advantage over posits for the hardware designer: the fixed location of bits for the exponent and the fraction mean they can be decoded in parallel. With posits, there is a little serialization in having to determine the regime bits before the other bits can be decoded. There is a simple workaround for this in a processor design, similar to a trick used to speed the exception handling of floats: Some extra register bits can be attached to each value to save the need for extracting size information when decoding instructions.

    The proposed system also lacks NaN and separate positive/negative infinities, so it wouldn’t be a drop-in replacement.

    Ah, Apache Commons: for those who felt Java’s standard library wasn’t bloated enough already.

    (I kid, I kid, though it was always funny just how many basic features seemed to be missing from Java back in the day despite its massive bundled library, leading to seemingly every major project adding Commons as a dependency. Not as much as thing these days AFAIK)
