1. This solution is much faster on re-invocation than the one without the persistent num_ones variable. Unless of course it is performed on a much larger (than num_ones) array of 32-bit integer.
2. It is essential to have the statement
The reason for this is that the floor() function has a problem with precision. If can fail with 32-bit integer that are close to 2^32.
