What is the current behavior?
The toBeCloseTo() matcher accepts only scalar numbers. Passing an array automatically fails the test.

What is the expected behavior?
For it to work when passing an array, to check that all items of received are close to expected.

Example:

expect([0, 1, 2]).toBeCloseTo([0.0001, 0.9999, 2]);

I think this is different from #3654 and #4057 in that it's simply extending this existing matcher in an intuitive manner, and isn't limited to extremely specific use cases.

Please provide your exact Jest configuration and mention your Jest, node, yarn/npm version and operating system.

Jest 20.0.4 with essentially the default Create React App configuration.

I don't think there is any benefit over calling the matcher individually on each item. If that's not sufficient, there is expect.extend to build your own matchers.

I know this is closed, and I'll write my own, but it would be really nice if .toBeCloseTo would just accept arrays.

For anyone coming in via a search, there is now https://www.npmjs.com/package/jest-matcher-deep-close-to

@cpojer the download count on that project disagrees
