Regex help please 1

[audiopro]

I am reading info from a text file and displaying it on a web page. The original brief was to put a line break after each full stop in the text.
Using:-

$ad_res[2] =~ s/\./.<br>/g;

How can I make it ignore the regex if there is a number before and after the full stop (ie 1.4 million)?

maybe this is good enough:

$ad_res[2] =~ s/\.(?!\d+)/.<br>/g;

Thanks Kevin - that works a treat but could you please explain how the (?!\d+) portion works.

Thanks - a bit of heavy going there but I have learned some useful new stuff.
For the benefit of archive - the replacement is not carried out if the full stop is directly followed by a digit.
