1. Giant numbers?

Ok, before you say
http://www.swox.com/gmp/
That doesnt work. The number is to large for it to calculate -,-.

You might be wondering what it is, it just so happens to be:
299,792,458^2.

Oh yes. Its big. Its also known as Speed Of Light Squared (Now I know why nobody says what that number is :P) I know the number is:

90,000,000,000,000 but, I cant tell my computer to hold that value (Yes, thats 90 quadrillion, I'm fairly sure thats rounded though).

So, is their anything thats even larger than swox's? Will an average computer be able to calculate it? -,-. I'm not to concerened with calculating speed, I just need to get the number.

Thank you .

2. Code:
```#include <iostream>
#include <float.h>

int main()
{
std::cout << DBL_MAX;
return 0;
}```
Don't give me that. The world is full of very large numbers, but we seem to do a pretty good job with dealing.

3. 89875517873681764

Edit
BTW, gmp can most definitely handle that, just without the commas

4. I had put in commas -,-.

Lol yeah, it can handle:
299792458^100

So it can definantly handle the square -,-.

Wow.... It took:

299792458^10011

O_o.

5. a long long is -9 quintillion to +9 quintillion i think

6. You know, a long double's range is: 3.4^-4932 to 3.4^4932. So I don't think it will be a problem. I'd use long though.

7. I wonder if logical ray-tracing achieves those speeds?

I guess any command can only move as fast as electricity allows...

So I would assume that tracing a beam of light and calculating its reactions to surfaces would be in now way even CLOSE to the speed of light...

90 quadrillion, that is as instantaneous as instantaneous can get.

Are the mathematics involved in physics as arbitrary as languages and words we assign objects?

Because obviously, nothing is calculating the way light reacts to things mathematically, it just happens, instantaneously, or at least at 90 quadrillion (what is it? MPH?)

Or is it? Matrix anyone?

The speed of light is 299,792,458 m/s (3.0x10^8), not 90 quadrillion (thats the speed of light squared, probably for einstein's e=mc^2).

Plenty of equations are based on the speed of light. Even if the number was that big, in physics the correct value would be used. Just look at G (6.67x10^-11), and thats a simple one used in first-year Physics.

As for these constants in game programming (gravity, light, forces, etc), I've read they are modified to logical numbers, depending on frames/sec, etc. Otherwise its most likely just programmed as instantaneous (you know light would have travelled around your game world 1000 times before the next frame, so why bother).
