( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Hi there Perlmonks! while gathering experience I tumbled over the Data Dumper package which just provides some interesting features. However while giving me single values of a certain line from a dat document, it can only return strings values. But unfortunately I need the number as a numerical value to further process it. Thats where I am struggeling. Here the code:
#!/usr/bin/perl -w use strict; my $resultnow='C:/Users/user/Desktop/solution.dat'; open (FILE, '<', $resultnow) or die "$resultnow File not found : $!"; my @lines = <FILE>; my $valuenow= $lines[9]; my @items=split' ',$valuenow; use Data::Dumper; #print Dumper(@items); my $val=Dumper($items[-1]); print $val; close (FILE);
In this case the value he is extracting is: -39.9999400000. but he marks it as a string '-39.9999400000'. But I would like to insert it in an equation to calculate something. So I need somehow a conversion or an alternative. Thank you again very much for your attention and help! Best regards

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
