NAME

Test::Deeply::Float - Test equality of data structure, compare numbers with tolerance

VERSION

This document describes version 0.001 of Test::Deeply::Float (from Perl distribution Test-Deeply-Float), released on 2018-08-07.

SYNOPSIS

use Test::More; # exports is_deeply(), etc
use Test::Deeply::Float; # exports is_deeply_float()

is_deeply      ({a => 1, b => 1.1234567}, {a => 1, b => 1.1234568}); # fail
is_deeply_float({a => 1, b => 1.1234567}, {a => 1, b => 1.1234568}); # pass
is_deeply_float({a => 1, b => 1.12345  }, {a => 1, b => 1.12346  }); # fail

To customize tolerance level:

$Test::Deeply::Float::EPSILON = 1e-9; # default is 1e-6

DESCRIPTION

This module exports is_deeply_float() which is just like Test::More's is_deeply(), except that when comparing two numbers (ints or floats) a tolerance is allowed to work around floating point rounding problem.

FUNCTIONS

is_deeply_float

Based on Test::More's is_deeply().

Test::Number::Delta and Test::Deep's num() can also compare floats with tolerance, but not in data structures.
