I have a program that reads each line of a file. The last line of the file may contain a number. I am trying to find a way to isolate the number within that line to give it value so it is a number and only a number and not a line of the file.
I can do:
$number = $_; # lets say the number is 83848;
and print number gives me:
However when I try to do something with this number like pass it along to an external subroutine with process_number($number) The subroutine can't interpret it.
Do I need to strip the number down some how? I tried to play with chomp() with no luck. Any help would be greatly appreciated as solving this would allow me to spend some time with my wife and kids.
