Why are floats not callable?

By using the __call__ method it is possible to define classes in a way that the instances will be callable objects. The __call__ method is called, if the instance is called "like a function", i.e. using brackets.

Why does Python use float instead of double?

These are almost the same - two names are provided because in some programming languages there are differences between float and double types. There are no such differences in python, but note that float is built in to python, while double comes from numpy, and hence is slightly different.

Why float is not used in Java?

Java does not use float as the default data type for floating point numbers. Java use the double as the default data type for floating point numbers. If we convert any float type value from float to double, there will be no data loss. If we convert any double type value from double to float, there will be data loss.
