Convert Nulls in Select statement

Is there a way to have a null field converted to a default value (say 0 for an int) in a SQL statement? Sybase had a coerse statement I believe that could do this. I need non null values to do computations with later, but the table allows nulls by default so I have to deal with them also. A simple function that converts a null to a default value on the fly would be fine if I could figure out how to do it. I'm new to Informix so any help would be appreciated.
