Or just use a double. It has 53 bits of mantissa.

See this a lot. Well if you really take it as a personal affront that many frontiersmen did this...please also refrain from taking credit for any collective positive accomplishment of humanity, like the US constitution, ending slavery, or m

I would suggest reading Sapiens by Yuval Harari to get some more perspective on what the agricultural revolution has done to this planet, and to humans. And for Native Americans just "up and changing their lifestyle"--nothing coul

This is horrible. Instead of bail, they should just have steeper fines for failure to appear and yet on the flipside the same guarantees afforded to jury duty as far as employment (i.e. can't be fired for having to appear in court). Th

This is not how verification works, generally. You have to prove your chip is correct.

by titzer 8y ago
For example, chips have flaws. Hardware designers work incredibly hard to verify that their chip designs are functionally correct, because the cost of a correctness bug can be catastrophic. With the proliferation of custom hardware designs,

This is pretty bad from a hardware/software verification perspective. People who care about correctness can just go home, I guess. It's amazing that we're gonna let these things on the streets. When you weigh almost 2 tons an

Well, you're in a combative mood, judging from all the replies you're posting, but I'll risk it. > It's not a healthy way to live Oh, agreed. Trust me. I've been neck deep in this one. It'll warp your mind.

Well, AC does help. But fast forward 100, 200, 500 years. After the food riots, the protests, political meltdown, the scarcity of clean water, the wars, the starvation and pandemics, the loss of coastal cities, the collapse of ocean ecosyst

Umm, wat. Alphabet has two classes of shares that trade under different ticker symbols, GOOG and GOOGL. Together they add up to $1.6t. The fact the author has overlooked this is astonishing. [edit: sorry, my mistake: the market cap reported

The OP is really spot on. For the commenters that seem to have some underlying fear that WASM apps will be another incarnation of a "window in a window" or some horrible bitmapped graphics pane that does not fit into the web model

Thanks again, Steve, for a very clear and sober explanation of this. It's like you're inside our heads! You grok.

Rounding modes aren't going away, so adding them to the instruction encoding is IMO cleaner, since it gets rid of ambient state that alters the semantics of instructions. It no doubt simplifies the internal implementation, since there

Your comment is incredibly insensitive and flippant. We can do better when we try to understand someone else's perspective--get into their narrative instead of 5 second superficial scanning and immediately turn off.
