... Perl resolves 0.0 to 0

As davido points out below, Perl stringizes 0.0 to '0':

c:\@Work\Perl\monks>perl -wMstrict -le
"my $f = 0.0;
 my $fs = qq{$f};
 print qq{stringization of 0.0: '$fs'};
 ;;
 $f = 0.5;
 $fs = qq{$f};
 print qq{stringization of 0.5: '$fs'};
"
stringization of 0.0: '0'
stringization of 0.5: '0.5'
