How can I detect this, I have been running some code for a few days to
develop some files and ran into the situation where I am getting the

14.95313 1.570813E-015 0

And my code is skipping some lines as it checks for any erroneous data:
next if grep (/[^0-9.-]/, @data);
But that thinks the scientific notation is bad. I searched the net and
didn't find anything. How can I match this specific pattern and convert it?
Thanks!

Don't write the regex yourself, use one of the ones in
Regexp::Common*. $RE{num}{real} is probably what you want.
As for how to make "1e3" into 1000, just add 0:
perl -e 'my $i = "1e3"; print $i, " ", $i+0, "\n"';
