Remove two minor compiler warnings/errors:

Found when building with the Fuchsia toolchain, which
uses a recent clang version:

- The constants '1.0f / 0x7FFFFFFF' and
  '1.0f / 0xFFFFFFFF' cannot be computed directly without
  losing one bit of accuracy, and the compiler was complaining
  about it, so use intermediate double values
  to get the correct, final result.

- The MemoryMapped class needs to be declared final to
  have a final destructor, otherwise the compiler complains
  with:

    error: class with destructor marked 'final' cannot be inherited from
    [-Werror,-Wfinal-dtor-non-final-class]
