long long int A = 3289168178315264;
long long int B = 1470960727228416;
double D = sqrt(5);

long long int out = A + B*D;

printf("%lld",out);

This gives result : -2147483648

I am not able to figure out why (it should be a positive result). Can somebody help?

I have a set of points double n[] on the plane z = 0. And I have another set of points double[] m on the plane ax + by + cz + d = 0. Length of n is equal to length of m. Also, euclidean distance between n[i] and n[j] is equal to euclidean distance between m[i] and m[j]. I want to rotate n[] in 3-D… >>> More
