Sometimes, especially with Informix, I woud be given numbers in engineering notation, rather than a regular digit as I expected. I needed a quick way to make the e-notation more readable. This snippet is what I generally use to do this.
# This is the important line
# s/([\.\d]+)e([-+]?\d+)/$1*10**$2/egi

sub de_engineer {
    my $val = shift;
    $val =~ s/([\.\d]+)e([-+]?\d+)/$1*10**$2/egi; 
    return $val;
}
