Very high int values turning negative

and Finally, My project is completely destroyed.
Thankfully I have made it's Backup before messing with numbers.....
Do Android support int64/long

 

It's rather unreasonable to store so many digits in a single numeric type. The user won't know if it's broken up.

More memory won't be the answer to every problem.

 

HeHe I am just a 12 years old awesome kid dev and my project isn't using a single thing that effects the performance much. Game was ready (before discovering the Int limit)
My game is giving great performance! so remove hardware please

 

sometime in past you were also like me low knowledge of development

 

As a general rule removing hardware makes your game unplayable. While there are plenty of people working on VR technology, no one has yet built a VCPU.

 

I meant to remove hardware from his post

 

Yes, int64 is supported on all platforms. It has nothing to do with 64-bit processing capability but rather represents the memory footprint of the number.

 

so it will kinda reduce the performance. So now i have no choice but keep lesser values. I may use strings after short values to represent them long like 10000000 = " M"

 

@Yash987654321 to be fair I was talking about the questions you've yet to ask and the problems you've yet to run into. It's fine if you're a newer & younger developer to not know everything, but your design decisions could bring more involved games to their knees. A lovely expression for saying that not very well designed or performant things will annihilate your framerate.

But we'll all be here to help if and when that ever happens

How many 64bit ints could a woodchuck chuck if a woodchuck had 3072MB of RAM?

Probably a lot... but for design and performance reasons, it might be better to not encourage people to design things with the biggest data structures they have available until they overflow

Now yer gettin' it! I'd also suggest scientific notation, so you can shorthand represent a number with any arbitrary number of digits.

10e123456

 

Yeah, just in the scripting forum please.

Switching a few key pieces of data to int64 will barely make a difference to your performance. But it sounds like you've got a ton of other problems going on, if you keep managing to completely break your project.

All that said, it wouldn't hurt you to be a little nicer to the volunteers that are trying to help you.

 

i think only floats can be converted in Es and all.

 

Technically easy or not I have always hated games that show very high numbers during combat etc. as it totally devalues the meaning of them. I guess some people like it that multiple digit numbers flood the screen when hitting mobs or scoring points but I always disable them with options/mod if possible. Same thing mostly for highscores that go beyond million or billion, at some point you just stop caring.

 

You use the array for calculation of big numbers (Bigger than Long), or you convert your big number to string and do calculations like that. But that will be very slow, which I`m talking from experience.

And store it however you want.

 

But he already has overflowed, which was the point of this thread.

384,000,000 if there was nothing else stored in ram.

 

I picked that number because my phone has like 2.7GB of RAM. It had more, but then the lollipop update happened.

I wonder how far we are from int5120

 

Keep in mind it was also quite common in games to just pad a 0 or two to the end of a stat to make the numbers feel bigger and more meaningful.

So adding 10 points or even 100 points could be just adding 1 to the actual internal value. So to a signed int that caps out at a little over 2 billion could represent 20 billion or even 200 billion and a short int can now handle 3,276,700 if there is no value less than 100.

 

Or use an alternative implementation. Saw this one linked in a Unity Answers response.

http://scrypt.codeplex.com

That's an RSA Encryption library I wrote for Silverlight 3 and Windows Phone as Microsoft didn't include RSA in Silverlight at the time and Silverlight 3 was based on .NET 3.5 and therefor didn't have BigInteger so I used (and credited) a third party BigInteger library. I had to fix a fair number of bugs in it but it was very similar in that it stored the number as a byte array and used bit shifting for the operators. If you do look at that, don't laugh at any shoddy code... that was my first ever attempt at C# since I had spent years at a company that was strictly VB .NET. :/

Edit: Also kindly ignore the fact that evidently people have found uses for Scrypt that I'd never thought of and with WP being on version 8 and Silverlight being dead for all intents and purposes, conversations / discussion / issues have gone on around it that I was totally unaware of. Guess I should have paid attention.

 

Lol remember that! But forgot if it was screensaver or one of these programs that allow for virtual destruction of your screen in variety of ways. Speaking of which, I'd need one.

 

Sorry for waking up a 2 months dead post but here are the scripts. I really don't understand what was going in the script. And don't judge my on the bases of this, I have learnt a lot form that time

 

Can you use a long instead of an int? Which is 64bit?
Interesting, you would only be able to have up to about 4.2 million dollars with an int.
But about 18.4 quadrillion dollars with a long. Which is just enough as some people estimate the cost of everything on earth as about 3 quadrillion dollars. Until inflation in a few years in which case your game will explode.
