+    These options determine the way floating point numbers, arrays and
+    other NumPy objects are displayed.
+
+    Parameters
+    ----------
+    precision : int, optional
+        Number of digits of precision for floating point output (default 8).
+    threshold : int, optional
+        Total number of array elements which trigger summarization
+        rather than full repr (default 1000).
+    edgeitems : int, optional
+        Number of array items in summary at beginning and end of
+        each dimension (default 3).
+    linewidth : int, optional
+        The number of characters per line for the purpose of inserting
+        line breaks (default 75).
+    suppress : bool, optional
+        Whether or not suppress printing of small floating point values
+        using scientific notation (default False).
+    nanstr : str, optional
+        String representation of floating point not-a-number (default nan).
+    infstr : str, optional
+        String representation of floating point infinity (default inf).
+    formatter : dict of callables, optional
+        If not None, the keys should indicate the type(s) that the respective
+        formatting function applies to.  Callables should return a string.
+        Types that are not specified (by their corresponding keys) are handled
+        by the default formatters.  Individual types for which a formatter
+        can be set are::
+
+            - 'bool'
+            - 'int'
+            - 'timedelta' : a `numpy.timedelta64`
+            - 'datetime' : a `numpy.datetime64`
+            - 'float'
+            - 'longfloat' : 128-bit floats
+            - 'complexfloat'
+            - 'longcomplexfloat' : composed of two 128-bit floats
+            - 'numpy_str' : types `numpy.string_` and `numpy.unicode_`
+            - 'str' : all other strings
+
+        Other keys that can be used to set a group of types at once are::
+
+            - 'all' : sets all types
+            - 'int_kind' : sets 'int'
+            - 'float_kind' : sets 'float' and 'longfloat'
+            - 'complex_kind' : sets 'complexfloat' and 'longcomplexfloat'
+            - 'str_kind' : sets 'str' and 'numpystr'
