Generate random numbers uniformly over an entire range

Question

I need to generate random numbers within a specified interval, [max;min].

Also, the random numbers should be uniformly distributed over the interval, not located to

Answer 1

If RAND_MAX is 32767, you can double the number of bits easily.

int BigRand()
{
    assert(INT_MAX/(RAND_MAX+1) > RAND_MAX);
    return rand() * (RAND_MAX+1) + rand();
}
