6 Number::Compare - numeric comparisons

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

11 my $c = Number::Compare->new(">1M");
12 $c->(1_200_000); # slightly terser invocation

15 Number::Compare compiles a simple comparison to an anonymous
16 subroutine, which you can call with a value to be tested again.
17
18 Now this would be very pointless, if Number::Compare didn't understand
19 magnitudes.
20
21 The target value may use magnitudes of kilobytes ("k", "ki"), megabytes
22 ("m", "mi"), or gigabytes ("g", "gi"). Those suffixed with an "i" use
23 the appropriate 2**n version in accordance with the IEC standard:

25
27 ->new( $test )
28 Returns a new object that compares the specified test.
29
30 ->test( $value )
31 A longhanded version of $compare->( $value ). Predates blessed
32 subroutine reference implementation.
33
34 ->parse_to_perl( $test )
35 Returns a perl code fragment equivalent to the test.
