   The new functions are:
 
-  * :func:`isinf` and :func:`isnan` determine whether a given float is
-    a (positive or negative) infinity or a NaN (Not a Number),
-    respectively.

+  * :func:`~math.copysign` copies the sign bit of an IEEE 754 number,
     returning the absolute value of *x* combined with the sign bit of
     *y*.  For example, ``math.copysign(1, -0.0)`` returns -1.0.
