Using regular expression in perl
Sorry, I am not sure if this thread belongs here.
I am new to perl and writing a regex for identifying if the user input lies in the set [0,100), i.e. the number must lie between 0-100, 0 included. It can be of form 0.000001, .00001, 90, 90.999153263, .12 etc
Following is the regex I wrote: $input =~ /dd?.d+|(dd?|.d+)/, but I am not gettinh the result. Can someone help me in this? Thanks in advance.
