\returns NumericalIssue if the input contains INF or NaN values or overflow occurred. Returns Success otherwise. */

\returns the inner size. * * \note For a vector, this is just the size. For a matrix (non-vector), this is the minor dimension * wit

Log base 2 for 32 bits positive integers. * Conveniently returns 0 for x==0. */
