64 Bit In Kerbal Space Program & Star Citizen
About | Information | History | Online | Facts | Discovery
I discuss the meaning of '64 bit support' in Kerbal Space Program and Star Citizen. Both project developers have spoken about 64 bit support in the last year or so and it's important to realise that the transition was to solve different problems for each project. So a little lesson in computer data seemed to be in order.

could 32 bit not store 4 gibibyte rather then 4 gigabyte?
-
Such knowledge, many mancrush... Wow.
-
if i have paid attention enough to starcitizens dev blogs its not just that they replaced values they figured out that the gpu was much more capable of doing maths on 32 bit floating point numbers so they did the same thing as kerbal did and divided space up in 32 bit sectors and afterwards converted them to a 64 bit whole once math was done. in my opinion pretty impressive

4:04 lol at MC hammer reference :)

Very informative video. Thanks Scott!

This is the reason why I can square root a number five times in the calculator on my iPhone, square it back the same number of times, and get a number that isn't that number..

Nothing to do with floating point precision, but the computer system on the Boeing 787 uses a 32 bit integer to keep track of up-time in ms. This value wasn't calculated in a 'checked' context and actually will overflow and loop from its maximum value back to zero. If this happened whilst in flight it would cause both engines to shut down, so the plane has to be completely shut down every so often to ensure this error never occurs.

I want more of this!

after watching this helpful video i ended up doing my own research as well and now i know a lot more why my KSP is struggling with my space station and what i need to do.
Thanks Scott, you're the best! :) -
Dear Scott, this has been one of your best videos ever. Thank you!
-
most educational (and entertaining) video I have seen in the last year!
-
Now I understand the issue much better. Thanks, Scott.
-
yay... longer numbers
-
Yes, 0.00635 meters is definitely 6.35 milliliters.
I'm sorry, I couldn't resist pointing out that slip. -
At 6:33 did you actually say "milliliters?"
Or perhaps some Scottish accent version of "the correct millimeters?"
I hope I'm not being too much a sniping jerk.
Actually I really liked your video(s), and can tell you put a tremendous effort into it. Thank you. -
Scott do you have a paytron?
-
That was a really good explanation. I was looking for someone to explain floating points to me thanks.
-
and this is the reason why i avoid floats when im programming, take that my highschool programming teacher looks like i did know more than you
