Subject: Re: Posits support under Musl libc?

I’ll bet anybody $100 that there will be practically useful quantum
computers before there’s a native hardware implementation of POSIT or UNUM
in a widely available general purpose processor (something a normal person
can buy).

Every trend in the industry right now favors fixed-point or low-precision
floating-point for AI. It’s known that one can build fast and accurate
arbitrary precision from AI widgets ( and
this, not crazy new formats with which nobody has any serious experience,
is the trend that numerical computing is going to exploit in the future.

If somebody believes in new floating-point formats, they should release a
library for a widely available FPGA and prove out the method on at least a
few million lines of numerical code to show the community why they need to
throw away decades of numerical software and rewrite a few billion lines of
codes in an as yet to be standardized datatype.
