Is that in the article? Or else, how do you know? I would like to write an implementation for fun in another language, but unum is getting mixed reviews here. Hence, it would be nice to see your source for it being incorporated into hardware.

At the bottom of the article, John mentions REX Computing, which I am the founder/CEO of. John has been a friend and advisor, and we have played around with minimal unum implementations, but haven't been able to commit the resources to a full one until after we tapeout our first chip in a little over a month (which will be using IEEE float). We also funded "dnautics" (a HN user who also commented here) to do a soft implementation of unum 1.0 in Julia.

Has REX explored other alternative binary floating point formats? Say, dec64 [0]?

How is dec64 different from Floating Point (IEEE 754)? It seems IEEE 754 allows for using base 10. What else do they do differently, do you know?

Besides using only base 10 representation, 1) all numbers are exact even if there are multiple representations. 2) because of 1), .1 + .2 = .3, eg, arithmetic follows the same rules you learned in school for 4 function arithmetic. 3) It supports upto 56-bit precise integer math without loss of precision. Look around YouTube for crockford talks about it. Usually they're JavaScript related. Or check dec64.com
