The value inside $operator (supposed to "." in case of "11.5") is interpreted as special character inside regular expression. Escape its special meaning as following

$celldata=~m{(.+?)\Q$operator\E(.*)}

You can better use split for this if you have only one "$operator" in a string

($left_str, $right_str) = split(/\Q$operator\E/, $celldata);
