Indeed, most of the times, both infinity and zero are only useful as
results (that were propagated from some special situation), not as
constants. But infinity is also a very useful sentinel value, that works
no matter what precision or range you are using.

There are many more ways to obtain infinity. Would you write a somewhat
complex function as a series of tests on numerical stability, or just
wait until the end to see if something blew up (i.e. test for infinity,
zero, nan)?
