in reply to Question about Numbers, Strings & SPLIT

You need to escape '.' in the regular expression like this:

  split /\./

'.' in a regular expression matches any single character, rather than the period character.

Please have a look through perlre.

Personally, I like to do:

my ($whole,$fract) = ($hjd =~ /(\d+)(\.\d+)?/);
If $fract isn't defined, it'll be evaluated as zero when used numerically.

    Bingo! You're a sanity saver! "." is a metacharacter! Of course! One blasted simple thing!

    THANK YOU!!!
