Problem with CORDIC 32 bits code in the code library.

Hi,
Posted this query in the code library forum also...
Seems problem with the code sent.
I think it is in every for loop:

Quote:
for (i=0;i<30>=0) {dx=X >>i;} else { dx=-X >> i;dx=-dx;}

I think it is missing if condition. Please correct me if I am wrong.

The problem is caused by posting code with HTML enabled.
To fix the problem, the person who posted the code has to delete
the existing code, paste in a fresh copy from their editor, and this
time select the tickbox to "Disable HTML in this post", before pressing
the Submit button.

Should now be fixed.

Although, I got trignometric values, of more than 3 digits accuracy, using cordic but still I have not been able to resolve the problem of calculating the distance between two points on the globe.
The problem now is that no matter if I use Haversine formula or other I cross the limits of int32.

Can anybody suggest any solution.

or Should I switch to 32bit microcontrollers.
Another question:
What may be the best choice for 32 bit microcontrollers which are cheap requiring the least like the compiler, the development and simulation boards and are easy to master.
Request suggestions in this regards too...
