I finished the second version of the prePEP for the Decimal data type. Sorry for the delay, but I restructured it to new (thanks list), and changing to a new house and deploying GSM in Argentina are not very time-freeing tasks, :p I don't post it to the list because it was blocked in c.l.p because it's size. You can reach it here: http://www.taniquetil.com.ar/facundo/python/prePEP-Decimal-0.2.html I'll appreciate any suggestion. Thank you! . Facundo
