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

31 $have_spec can be:
32
33 * a Number::Tolerant object
34 * an arrayref of args to Number::Tolerant->new
35 * a string to be passed to Number::Tolerant->from_string
36 * a literal number falls under this group
37
38 If the value is outside of spec, you'll get a diagnostic message
39 something like this:
40
41 given value is outside acceptable tolerances
42 have: 3
43 want: 5 < x
