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:

METHODS

->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.
