comparing numbers in a file
Hello, I'm searching for a quick method to read numeric values from a file or a defined variable and identifying the largest number. For instance if the following numbers are in a file or defined to a variable:
09192007 09202007 09182007 09172007 09162007
What "short" method could be used to id "09202007" as being the largest number read in?
Thanks much!

je::number
JE::Number(3pm) User Contributed Perl Documentation JE::Number(3pm)
NAME
JE::Number - JavaScript number value
SYNOPSIS
use JE;
use JE::Number;
$j = JE->new;
$js_num = new JE::Number $j, 17;
$perl_num = $js_num->value;
$js_num->to_object; # returns a new JE::Object::Number
DESCRIPTION
This class implements JavaScript number values for JE. The difference between this and JE::Object::Number is that that module implements
number objects, while this module implements the primitive values.
Right now, this module simply uses Perl numbers underneath for storing the JavaScript numbers. It seems that whether Perl numbers are in
accord with the IEEE 754 standard that ECMAScript uses is system-dependent. If anyone requires IEEE 754 compliancy, a patch would be
welcome. :-)
The "new" method accepts a global (JE) object and a number as its two arguments. If the latter is an object with a "to_number" method whose
return value isa JE::Number, that object's internal value will be used. Otherwise the arg itself is used. (The precise details of the
behaviour of "new" when the second arg is a object are subject to change.) It is numified Perl-style, so 'nancy' becomes NaN and
'information' becomes Infinity.
The "value" method produces a Perl scalar. The "0+" numeric operator is overloaded and produces the same.
Stringification and boolification are overloaded and produce the same results as in JavaScript
The "typeof" and "class" methods produce the strings 'number' and 'Number', respectively.
