This reverts commit d1156fcb56891fb1a426c3e8331a51d47f98a1b8. This patch fixes the reported incorrect formatting changes and adds tests for them. The performance should be unaffected, since there are no significant changes required to fix the bugs. Specifically, a `>` was changed to a `>=` to also add a `+` in the zero case, and we're checking for zero now before printing the octal and hexadecimal prefixes. Closes #131710
