I don't see how that couldn't run into similar problems. I would use `clamp(old_hp * (new_maxhp / old_maxhp), 1, new_maxhp)` (assuming that old_hp >= 1).

If you assume that all three numbers are small integers, doing the division last minimizes precision loss (and doesn't have any loss if the accurate result is representable as a float).

Otherwise you get loss from the division and then multiply that loss (by >1).

It could, but only at very large values. It's at least the much more robust solution.
