Avoid casting where possible

[AreaZR]

We should try to avoid changing the signedness of unsigned variables where possible.

@fxlb I fixed the mistake.

Your title is Prefer unsigned variables where appropiate. Some changes are not related with this title. What are the problems you want to solve?

[AreaZR]

Avoid casting where possible.

@fxlb I hope this works for you!

The commit summary says "avoid casting", but the diff removes two type casts and adds three type casts. This needs to be a bit more focused.

@infrastation Done!

@fxlb Done!

As these changes are now, they still replace two type casts with three type casts and make a number of other unrelated changes, so I find it best to reject the proposed changes in order to be able to prioritize more important pending work. Thank you for your time anyway.
