@cfajohnson: Of course without using test command ;-)

Well, pointless maybe but it's not so easy to do :-) I've already done a half but it took me three hours ;-)

number::compare

Number::Compare(3pm)					User Contributed Perl Documentation				      Number::Compare(3pm)

NAME

       Number::Compare - numeric comparisons

SYNOPSIS

	Number::Compare->new(">1Ki")->test(1025); # is 1025 > 1024

	my $c = Number::Compare->new(">1M");
	$c->(1_200_000);			  # slightly terser invocation

DESCRIPTION

       Number::Compare compiles a simple comparison to an anonymous subroutine, which you can call with a value to be tested again.

       Now this would be very pointless, if Number::Compare didn't understand magnitudes.

       The target value may use magnitudes of kilobytes ("k", "ki"), megabytes ("m", "mi"), or gigabytes ("g", "gi").  Those suffixed with an "i"
       use the appropriate 2**n version in accordance with the IEC standard: http://physics.nist.gov/cuu/Units/binary.html

METHODS

   ->new( $test )
       Returns a new object that compares the specified test.

   ->test( $value )
       A longhanded version of $compare->( $value ).  Predates blessed subroutine reference implementation.

   ->parse_to_perl( $test )
       Returns a perl code fragment equivalent to the test.
