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.

- * ``copysign(x, y)`` copies the sign bit of an IEEE 754 number,
+ * :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.
