   - `long long int` or `unsigned long long int` are 64-bit
     - avoid using 64-bit numbers as I still build for 32-bit systems.
     - two `long`s are required to make Windows happy.
+    - prefer using `int64_t` or `uint64_t` for this specific case.
   - `size_t` are 32-bit or 64-bit, depending on architecture.
 - in float/double operations, always use decimal and `f` if single-precision.
   - e.g. `1.0f` or `1.0` instead of `1`.
