Thank you so much. This is such a beautiful implementation!

It works very well if my search value has only 2 digits after the ".". I cannot match anything if I search for the following value with 3 digits after the "." (sorry I haven't specified the forms it can take). Is it possible to make your solution more flexible in terms of number of digits?

my $input = 7.255;
