I started a PR and some simple examples were added. It is helpful for those who
are new to IEEE-754.
According to Jelle's comments, the behavior of `float('nan') is float('nan')`
may be changed in the future, so I just omit it

Indeed, if you use Python keywords or other invalid Python names as keys of
TypedDict, we must use the equivalent forms as follows:
```
Point2D = TypedDict('Point2D', {'x': int, 'y': int, 'in': str}) # OK
Point2D = T
