Speed has a lot to do with it. Have you timed some decimal operations
against their floating-point counterparts? It might be possible to build
a version of Python that used decimal instead of floating-point but it
certainly wouldn't be trivial: consider the use of C language libraries
that know nothing of Python's decimal representation.
