Is there a simple term for "the rest of the pie"?

Is there a one- or two-word term that means the difference between 100% and the given percentage? For example, given 83%, is there a mathematical term for 17%? Kind of like how 45 degrees would be the "supplementary angle" to a 135-degree angle. A character on a TV show recently called it the "inverse," which is technically not correct.

Update:

P.S. This has nothing to do with pi.

Update 2:

I guess "complement" might be a good term for this, as long as one doesn't confuse it with the geometric sense. But is there a more official, established, accepted term among mathematicians and scientists?

    No, there isn't. In particular contexts of course there are context-specific terms that would work. For example if the percentage is the portion of men in the population, then "the rest" is the portion of non-men in the population. If 30% of the advertising budget is for online ads then "the rest" is the budget for non-online ads, etc. I think the reason there is no general term in use is that in most contexts, the context gives a handy name for "the rest".

    Frankly, if one has to use a general term, I think "the rest" is as good as any. One is always free to invent or choose something mathier sounding (as the person on TV apparently did), but then one is in the position of having to explain to the world, every time one uses the term, what one means, so it isn't any shorter. I wouldn't go so far as to say it is "technically not correct," but definitely a waste of time.
