ok, i understand the formula now. thanks! :)

By portable do you mean 32-bit and 64-bit systems?

ok, i was able to get a solution for the bit wise rotation without using the sizeof() function for rotate right: :)


temp = n1 & 0x1;
n1 >>= 1;
n1 = n1 | (temp << 31);



however, im still...

Thanks for the reply.

ok i played with it a bit using hexadecimal 49 and 10. I got the same answer (49000) even though i just used:

(x << shift) | (x >> (x - shift)). :confused:

Hi,

Im trying to create a bit rotate function for a "hexadecimal calculator". I found a code in wikipedia that seems to work:



unsigned int x; unsigned int y; /* ... */ y = (x << shift) |...
