deep-close-to v1.0.2

deep-close-to

Node's assert.deepEqual() but with configurable comparator. The default comparator compares the absolute difference to be below an epsilon, suitable for floats.

example

var closeTo = require('deep-close-to');
console.dir([
    closeTo(
        { a : [ 2, 3 ], b : [ 4 ] },
        { a : [ 2, 3 ], b : [ 4 ] }
    ),
    closeTo(
        { x : 36/5, y : [6] },
        { x : 72/10, y : 6 }
    )
]);

methods

var closeTo = require('deep-close-to')

deepEqual(a, b, opts)

Compare objects a and b, returning whether they are equal according to a recursive equality algorithm.

If opts.strict is true, use strict equality (===) to compare leaf nodes. The default is to compare their absolute difference to be below 0.0000001. Number.EPSILON was not used because numeric errors are often bigger than it.
