You said using equivalence for floats that store integers is fine. here is a link: [1]. The point of my example was to show that that is not the case for numbers that are easily stored by an int that's the same size as a float. I've not use

i guess that's what a i get for not double checking my math. here's a revised version that (as long as i haven't made any other math mistakes) still fits within a 32 bit signed int but doesn't guarantee simple equality: float a = 0.0;

by joshAg 14y ago
If you mean arithmetic on floating point numbers that only store integers, then no equivalence is not ok, because there are examples where bit equivalence fails. One example is repeatedly adding 1.0 to a float something like 1 trillion time

by joshAg 14y ago
even just addition and multiplication with floats make simple equivalence a horrible idea, due to uncertainty. For example: float a = 1.0; float b = 1000.0; for (int i = 0; i < 1000000; ++i) a+=1.0; b *= b;

Attmepting to just use simple equivalence with any floating point type a horrible idea to begin with, even without NaNs. You should instead declare equivalence if the absolute difference between the two numbers is less than some bound based

I don't have a source I can find easily, but I believe the older rovers had a 10Mbs uplink.

the last rovers were solar powered, which is partly why they were dormant in the winter and at night.

when we start building "breeder" reactors again. Plutonium is a byproduct of the breeder reactors when they create the type of uranium that can be used for nuclear bombs (this is one of the reasons that breeder reactors aren't popular). I w

Yes, adding noise will be unavoidable, but not broadcasting an ssid means unsuspecting people won't try and connect to these pseudo AP's. To cut down on the interference caused by the added radio noise one could either hardwire all the pseu

i like your style. might i suggest finding out how the wifi scanners work, and then creating a bunch of dummy wifi connections with well hidden embedded systems (of course, set them up with a hidden ssid so it doesn't interfere with people

for someone who'd never flown anything other than coach, the experience was mindblowing, especially since the upgrade was only $50 at the airport. i'd love to fly first or business again when i eventually go to europe, but as a hypothetical

reddit partially gets around this by allowing users to create their own subreddits. i've been much happier with reddit since i unsubscribed from all the default subreddits.

if US judges took the same "living tree" approach to the constitution that Canadian judges do to theirs, I'd agree with you, but since they instead try and discover "original intent" I think it just unnecessarily introduces confusion over w

the problem with the 4th amendment (really with any of the amendments jefferson wrote) is that it uses vague words like 'unreasonable' and 'probable' that have to be determined/explained in a later trial, which makes it much easier to skirt
