Trailing zeros in report

I have a report which has a "zip code" field.

entries are having 4 unwanted trailing zeros.

So a zip code like 02895 looks like 028950000

and a zip code like 08610 looks like 086100000

It is important to note that in the 2nd example only the last 4 zeros are useless...

is there any expression that can allow me to get rid of the last 4 zeros in the output?
