org.json.JSONArray.optDouble()
Get the optional double value associated with an index. NaN is returned if there is no value for the index, or if the value is not a number and cannot be converted to a number. @param index The index must be between 0 and length() - 1. @return The value.

    public void testArray() {
        JSONArray json = OTJson.array("string", 123, 123.456, true, false, null);
        Assert.assertNotNull(json);
        Assert.assertEquals("string", json.optString(0));
        Assert.assertEquals(123, json.optInt(1));
        Assert.assertEquals(123.456, json.optDouble(2), 1e-15);
        Assert.assertEquals(true, json.optBoolean(3));
        Assert.assertEquals(false, json.optBoolean(4));
        Assert.assertEquals(null, json.opt(5));
