The prefix for the first commit should just be fs: instead of feat(internal/fs):.

It would be nice to also add a test for floating point numbers.

It's better to use common.expectsError in our tests.

@starkwang I must disagree. The original reason for using common.expectsError is that it allowed to use the error object. Now, assert.throws is more powerful than common.expectsError due to a much better error message output and since that feature was added to assert.throws.
