NAME

       Test::Tolerant - test routines for testing numbers against tolerances

VERSION

       version 1.709

SYNOPSIS

         use Test::More;
         use Test::Tolerant;

         my $total = rand(6) + rand(6) + rand(6);
         is_tol(10, [ qw( 3 to 18 ) ], "got an acceptable result from random dice");

         done_testing;

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.

       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.

FUNCTIONS

   is_tol
         is_tol($have, $want_spec, $comment);

       "is_tol" is the only routine provided by Test::Tolerant, and is exported by default.  It
       beahves like "is" from Test::More, asserting that two values must be equal, but it will
       always use numeric equality, and the second argument is not always used as the right hand
       side of comparison directly, but it used to produce a Number::Tolerant to compare to.

       $have_spec can be:

         * a Number::Tolerant object
         * an arrayref of args to Number::Tolerant->new
         * a string to be passed to Number::Tolerant->from_string
           * a literal number falls under this group

       If the value is outside of spec, you'll get a diagnostic message something like this:

         given value is outside acceptable tolerances
             have: 3
             want: 5 < x
