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

Number::Compare - numeric comparisons

Number::Compare->new(">1Ki")->test(1025); # is 1025 > 1024
my $c = Number::Compare->new(">1M");
$c->(1_200_000);                          # slightly terser invocation

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

->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.
