I wrote a short program to sort through a long output file for various things, but the data in there was in scientific notation. The format is 1.12345E+05, and may have a leading -. So I wrote up this small subroutine: 
sub scicon {
    my @result;
    for my $i (0 .. $#_) {
        my $string_in = $_[$i];
        $string_in =~ /(-?\d.\d+)E(.\d+)/;
        my ($const, $expon) = ($1, $2);
        $result[$i] = ($const * 10 ** $expon);
    }
    return @result;
}

As I'm new to the language (and programming, really), and this gets used 3 or 4 times per line of a million+ line file, I was wondering if there's a better way or even a built-in command for this. Thanks.
