in reply to Match number >= 0 and <1

It could be more concise, and you don't need the alternation:

my ($num) = $_num =~ /^0?\.\d+$/;
Interpreted as: zero or one zeroes, a period, followed by digits.

    "0" is not legal according your regexp. I did the same mistake up above. Also, you removed the necessary capture.
