One workaround is to *impose* precision: here, you want equality up to the first two decimal places, so you could multiply your numbers by 100 and take the int() value of them to compare. Here's a subroutine: 

sub cmp_dollar {
   my ($c, $d) = map { int( $_ * 100 ) } @_;
   $c == $d;
}

This oughta deal with the trailing \n issue, too, as that will be ignored by the automagic string-number conversion.

perl -e 'print "How sweet does a rose smell? "; chomp ($n = <STDIN>); 
+$rose = "smells sweet to degree $n"; *other_name = *rose; print "$oth
+er_name\n"'
