Can anyone please tell me how can I convert this float number: 12.25 to binary? I know how to convert the "12" but not the 0.25

Any help is much appreciated. Thanks

void transfer(double x) {
  unsigned long long * p = (unsigned long long * ) & x;
  for (int i = sizeof(unsigned long long) * 8 - 1; i >= 0; i--) {
    cout << (( * p) >> i & 1);
  }
}
