Cooking results in some round-off error

[RockPolish]

For example, an egg gives -10 hunger, and when I add one egg to a frying pan, I get a dish with -10 hunger, and instead of the egg disappearing, it has -1 hunger.

This is really annoying because you end up with 10+ eggs that give only -1 hunger and you can't add more than 3 to a dish without making you unhappy.

As another example, ham gives -60 and when adding it to a dish (which adds -10 hunger to the dish), the ham now gives -51, and then -42, etc

I don't have any mods and am running the latest stable version, this is in singleplayer.
