A function in the mathematical sense is something a little different than a function in the programming sense.

No, it depends on the context:

Under the imperative programming paradigm, "function" can refer to anything: subroutines with and without return values; deterministic and non-deterministic; and with and without side effects.

Under the functional programming paradigm, "function" nowadays usually has the mathematical meaning... well, at least in hardcore functional-programming circles (i.e. between Haskell programmers).

The differentiation between function and procedure a-la Pascal is, frankly, uninteresting and mostly useless.
