Ideally no. Deflation is pretty bad for an economy. Currencies might eventually be redenominated which is basically where a new currency is issued to replace the existing one at a set exchange rate.
For example the dollar might be replaced with the super dollar, and 1 super dollar equals 100 dollars. Banks etc would accept both for a number of years but only pay out in the new currency, accounts etc would switch to being denoted in the new currency.
If inflation is kept at 2% you would on average need to drop a zero about once ever 120 years.
