     Parameters
     ----------
-    precision : int
+    precision : int, optional
         Number of digits of precision for floating point output (default 8).
-    threshold : int
+    threshold : int, optional
         Total number of array elements which trigger summarization
         rather than full repr (default 1000).
-    edgeitems : int
+    edgeitems : int, optional
         Number of array items in summary at beginning and end of
         each dimension (default 3).
-    linewidth : int
+    linewidth : int, optional
         The number of characters per line for the purpose of inserting
         line breaks (default 75).
-    suppress : bool
+    suppress : bool, optional
         Whether or not suppress printing of small floating point values
         using scientific notation (default False).
-    nanstr : string
+    nanstr : string, optional
         String representation of floating point not-a-number (default nan).
-    infstr : string
+    infstr : string, optional
         String representation of floating point infinity (default inf).
