Is there an formula stating the number of times you would have to halve a number to reduce it to some value less than or equal to $1$?
For example, for $6$ it takes three halvings: $6/2=3$, $\ 3/2=1.5$, $\ 1.5/2=0.75$.
Also, is there a representation using the floor function in conjunction?
For example, for $6$ it takes two halvings if we round each intermediate result down: $\lfloor 6/2\rfloor=3$, $\ \lfloor 3/2\rfloor=1$.
