  /**
   * In C++ an unsigned to signed cast where the source value cannot be represented in the destination
   * type results in an implementation defined destination value. Unlike C, C++ does not allow a trap.
   * This makes "(S)(D)s == s" a possibly useful test. However, there are two cases where this is
   * incorrect:
   *
   * when testing if a value of a smaller signed type can be represented in a larger unsigned type
   * (int8_t)(uint16_t)-1 == -1 => (int8_t)0xFFFF == -1 => [implementation defined] == -1
   *
   * when testing if a value of a larger unsigned type can be represented in a smaller signed type
   * (uint16_t)(int8_t)0xFFFF == 0xFFFF => (uint16_t)-1 == 0xFFFF => 0xFFFF == 0xFFFF => true.
   *
   * Consider the cases:
   *   u = unsigned, less digits
   *   U = unsigned, more digits
   *   s = signed, less digits
   *   S = signed, more digits
   *   v is the value we're considering.
   *
   * u -> U: (u)(U)v == v, trivially true
   * U -> u: (U)(u)v == v, both casts well defined, test works
   * s -> S: (s)(S)v == v, trivially true
   * S -> s: (S)(s)v == v, first cast implementation value, second cast defined, test works
   * s -> U: (s)(U)v == v, *this is bad*, the second cast results in implementation defined value
   * S -> u: (S)(u)v == v, the second cast is required to prevent promotion of rhs to unsigned
   * u -> S: (u)(S)v == v, trivially true
   * U -> s: (U)(s)v == v, *this is bad*,
   *                             first cast results in implementation defined value,
   *                             second cast is defined. However, this creates false positives
   *                             uint16_t x = 0xFFFF
   *                                (uint16_t)(int8_t)x == x
   *                             => (uint16_t)-1        == x
   *                             => 0xFFFF              == x
   *                             => true
   *
   * So for the eight cases three are trivially true, three more are valid casts, and two are special.
   * The two 'full' checks which otherwise require two comparisons are valid cast checks.
   * The two remaining checks s -> U [v >= 0] and U -> s [v <= max(s)] can be done with one op.
