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:

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.
