* subroutine, which you can call with a value to be tested again.
|

|
|
* Now this would be very pointless, if NumberCompare 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
|

|
|
* Based on the Perl Number::Compare module.
