It's ever so slightly faster to stick to stick to 64-bit arithmetic and
it avoids clang tidy being unhappy about the implicit widening.

disable incredibly impractical clang-tidy check
...
bugprone-easily-swappable-parameters is completely impractical for real
world usage. It's a reasonable thing to consider as part of API design
but it mostly applies to having APIs taking a lot of parameters. It's
unreasonable to disallow APIs simply taking 2 integer parameters even as
a loose guideline.
