+    Parameters
+    ----------
+    device : {None, string, SyclDevice, SyclQueue}, optional
+        An array API concept of device where an array of default floating type might be created.
+        The `device` can be ``None`` (the default), an OneAPI filter selector string,
+        an instance of :class:`dpctl.SyclDevice` corresponding to a non-partitioned SYCL device,
+        an instance of :class:`dpctl.SyclQueue`, or a `Device` object returned by
+        :obj:`dpnp.dpnp_array.dpnp_array.device` property.
+        The value ``None`` is interpreted as to use a default device.
+    sycl_queue : {None, SyclQueue}, optional
+        A SYCL queue which might be used to create an array of default floating type.
+        The `sycl_queue` can be ``None`` (the default), which is interpreted as
+        to get the SYCL queue from `device` keyword if present or to use a default queue.
+
+    Returns
+    -------
+    dt : dtype
+        A default DPNP floating type.
