[Zope] ZSQL returns integer only

The Oracle8i recordset I'm retrieving includes a few columns which are NUMBER(10,0) format which are milliseconds. I would like to divide each by 1000 and use the ROUND function to return a result with one decimal place, e.g. ROUND(column1/1000, 1). This works as expected in SQL*Plus. It returns the results as a number formated to one decimal place. ZSQL however returns only an integer. Any suggestions on how to get the decimal places to show?
