Agreed. I'll work on the mathematical approach now.

Thanks a lot.

And another way to calculate the gap between the numbers would be:

0.00000000000000001 (the minimum variation on the mantissa) * 2 ^ 101 = 253530120045645.880299341

Then we are able to...

Yeah I had forgotten about the 15 decimal digits of precision on doubles.

So I guess the numbers are this:

Original number is 1267650600228229401496703205376.000000, which is represented as...

Actually I think my reasoning was right, but I am not sure about the numbers.

Testing manually I found that the minimum number that will produce a change on the original double...

Ahh, I think I get it now. In fact I used the frexp function to see how the computer was storing that number. Here's the code:



#include <stdio.h>
#include <float.h>
#include <math.h>

int...

Hi,

For some reason I am having trouble manipulating large double numbers in C. For example, with the following code:


#include <stdio.h>
#include <math.h>

int main(){
double x;
