.IX Header "SYNOPSIS"
.Vb 2
\& use Number::Tolerant;
\& use Number::Tolerant::Constant;
\&
\& my $range  = tolerance(10);
\& ref $range; # "Number::Tolerant" \-\- w/o ::Constant, would be undef
.Ve
.SH "DESCRIPTION"
.IX Header "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.
.PP
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.
.SH "PERL VERSION"
.IX Header "PERL VERSION"
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.
.PP
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.
