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



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.
