Expand description
Calculates the ceiling of the base-2 logarithm of a number.
Returns the ceiling of the base-2 logarithm of a positive float.
$f(x) = \lceil\log_2 x\rceil$.
§Worst-case complexity
Constant time and additional memory.
§Panics
Panics if self is infinite, NaN, or less than or equal to zero.
§Examples
See here.
