SYNOPSIS

        package foo;
        use Meta::Math::MinMax qw();
        my($object)=Meta::Math::MinMax->new();
        $object->add(5);
        $object->add(4);
        $object->add(11.5);
        my($min)=$object->get_min();#should be 4
        my($max)=$object->get_max();#should be 11.5

DESCRIPTION

This is a simple Min/Max collector. Meaning - while you are in some kind of process, and would like to get some infomation on sets of numbers you are working with, create an instance of this object, throw numbers it's way and at the end of your process it will tell you what the minimum and maximum values were. This saves you the code to do it in your object.

The memory consumption of this object is quite low since it only remembers the min and max values.

Another advantage of using this kind of object is that you can supply yet other objects with the same interface which do other things like keep the mean value, the variation and other statistics.

If no values are thrown then the get_min and get_max methods will return "undef".

FUNCTIONS

        BEGIN()
        add($$)
        reset($)
        TEST($)

FUNCTION DOCUMENTATION

BEGIN()

This block sets up the constructor and attribute methods for this object which are "min" and "max".

add($$)

Throws another value into the pot. The minimum and maximum values get updated accordingly.

reset($)

This method will reset the MinMax object so that it could be used for a new set of numbers.

TEST($)

Test suite for this module.
