Yes, confirmed that this is not a bug, but just one of the many consequences of approximating real numbers by floating-point numbers.

You may be interested in math.log2 and/or int.bit_length. math.log2(x) *may*  give you more accurate results than math.log(x, 2) when x is a power of two, but there are no guarantees - we're at the mercy of the C math library here.
