Manual Reference Pages - NUMBER::TOLERANT::CONSTANT (3)
Number::Tolerant::Constant - a blessed constant type
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 hadnt returned a blessed object.
