Based on context they're the multiplication operator, usually read out
loud as "times". They're usually distinguished from decimal points not by
how bold they are, but by being placed on the center of a line rather than
at the bottom of it; in ASCII people usually use asterisks (*) instead
of periods since there's no "period up higher" character.

I've got to say I'm curious: how is it that you haven't seen a dot
used to signify multiplication, but you have seen a carat (^) used to
signify exponentiation?
