Number::Tolerant::Constant - a blessed constant type
version 1.708
use Number::Tolerant; use Number::Tolerant::Constant; my $range = tolerance(10); ref $range; # "Number::Tolerant" -- w/o ::Constant, would be undef
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.
