NAME

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

VERSION

version 1.708

SYNOPSIS

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

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

DESCRIPTION

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.
