Hello Monks,

I have this script that I use when I need to check perl's data type size in whatever machine I sit on (see below).

As you can see, it uses Config to report integers and double.

Does anybody know how to ask about single precision? Hint: it is not singlesize or floatsize.

Thank you,

Nr1culprit

The script:

#!/usr/bin/perl

use strict;
use warnings;
use Config;

print 'short ',      $Config{shortsize},    "\n";
print 'int ',        $Config{intsize},      "\n";
print 'long ',       $Config{longsize},     "\n";
print 'longlong ',   $Config{longlongsize}, "\n";
print 'doublesize ', $Config{doublesize},   "\n";
print 'byte order ', $Config{byteorder},    "\n";

exit;

Update:I got it to work just fine with pc88mxer suggestion.

Thank you.

In case you are interested, my little script now looks like this:

#!/usr/bin/perl

use strict;
use warnings;
use Config;

print 'short ',      $Config{shortsize},     "\n";
print 'int ',        $Config{intsize},       "\n";
print 'long ',       $Config{longsize},      "\n";
print 'longlong ',   $Config{longlongsize},  "\n";
print 'f via pack ', length(pack("f", 1.1)), "\n";
print 'doublesize ', $Config{doublesize},    "\n";
print 'byte order ', $Config{byteorder},     "\n";

exit;
