perl v5.36.0                                       2023-01-08                    Number::Tolerant::Constant(3pm)

       When Number::Tolerant is about to return a tolerance with zero variation, it will return a constant
       instead.  This module will register a constant type that will catch these constants and return them as
       Number::Tolerant objects.

       I wrote this module to make it simpler to use tolerances with Class::DBI, which would otherwise complain
       that the constructor hadn't returned a blessed object.

       Number::Tolerant::Constant - a blessed constant type

       This library should run on perls released even a long time ago.  It should work on any version of perl
       released in the last five years.

       Although it may work on older versions of perl, no guarantee is made that the minimum required version
       will not be increased.  The version may be increased for any reason, and there is no promise that patches
       will be accepted to lower the minimum required perl.

        use Number::Tolerant;
        use Number::Tolerant::Constant;

        my $range  = tolerance(10);
        ref $range; # "Number::Tolerant" -- w/o ::Constant, would be undef
