What Hacker News says
2 sourcesyeah I was going to ask, what's the deal with all those wasted bits?
I'm not a floating-point fan (I do all computations in integer wherever possible/feasible), but I've been following the universal number story since it was announced because it seems less painful/gross than IEEE floating-point on many fronts, here's a github with a good about page about it: https://github.com/stillwater-sc/universal
