Actually, that was a cleaned-up example, the actual one was using 
if( $cost) 
{
    ....
}

[download]
but I was getting different results (ie if() was true/false) depending on whether the $cost of 0.00 was extracted via DBI::MYSQL and then left untouched, or extracted via DBI::MYSQL and then added to an integer zero.
Took me a while to figure out why the optional code path was /was not being followed.
ie not just an academic qn and nothing to do with printing as such.
