Re: getting numeric data from a file into an array

...I'm not sure how to do it

What have you tried so far? Just so you know, we're usually happy to help, but this is not a code writing service or a place to get homework answers.

And welcome to PerlMonks!

I should have been more specific. I was suspicious that matching reg exp would do the trick. Here is what I have so far: `# read in times open MYFILE, "<$dir/structs/times"; my @temptimes = <MYFILE>; close(MYFILE); print "$#temptimes\n"; my @strtimes; for (my $i = 2;$i <= $#temptimes;$i++){ if ($temptimes[$i] =~ m/(\d+.\d+)/){ print "$1\n"; } }` [download] I'm having trouble reading the other two values and storing them in an array. I figured I could just multiply by 10^3 to account for the "E+03", as I didn't know how to deal with the "+" sign. Sorry if it seemed like I'm looking for homework solutions - in fact this is not homework. I can do this in other languages, I just want to learn Perl.	[reply] [d/l]

  if ($temptimes[$i] =~ m/(\d+.\d+)/){
    print "$1\n";
