Checks are by large the primary way business pay each other down here in Chile,
and they require to have the number written as words. It is also quite common to
print this in quotes and invoices.

It is one of the most common exam questions for programmers here because it is
so ubiquitous. I put out a small library in Delphi, which is not
interesting by its own,
but the test cases are quite complete:

As you can see, numbers in Spanish are not straight-forward. 11 is "once", 21 is
"veintiún" or "veintiuno" depending where it is, 31 is "treinta y uno"...

In my opinion, it is not feasible to do this using a one-size-fits-all
approach. Plug ins
may be a good idea.
