Thank you for such a quick and informative reply all of you.
I am apologizing for my ignorance, and am so ashamed because of it.
I am trying to extract a three variables (integer numbers): n31, n32, n33, for a specific value of "f". On top of that there is a third variable "f0" which should vary from 10^-26 to 10^-5.
So what this code should enable me is that for some "f" which I will get from my press machine and read it, I should search this C code for the same (or similar) "f" value, and read what are the values for f0, n31, n32, n33 in accordance to that "f" value.
An example: If I get a value of 5e-10 from my machine press, I will look for the some (or similar value) in C code and when I find that value I will be able to get the f0, n31, n32, n33 from it. Like this:
3.63078e-006 -5.09259e-010 27 27 28
I am I still puzzled why am I getting a negative values for "f" (-5.09259e-010 ?)
This is a structural analysis study of a piston press. The f, f0, n31, n32, n33 are coefficients needed in order for the design calculation to be done. As there are few equations with few variables, it seems writing a C code with loop and then getting the values from it is only available solution, as I did not succeed in calculating these factors by hand.
@std10093: I tried changing the parts of the code the way you told me, like this:
Still the most lower value for "f0" is around 1.2e-011.
printf("# f0, f, n31, n32,n33\n");
printf("%g %g %i %i %i\n",f0,f,(int)n31,(int)n32,(int)n33);
And I also run the code you gave me (the one for the maximum value) and got something similar like you:
Process returned 0 (0x0) execution time : 0.016 s
Press any key to continue.
@Adak. Here is the content of the limits.h file I found in "C:\Dev-Cpp\include" folder. What part of it do I need to change in order to increase that lower limit of 1.2e-011?

From the above code:
Is that what I need to change/increase ??
