"How knows python that it is a float, or a string?" Sorry this was bad 
expressed. I want to create a new data type, which inherits from float. I 
just know the "dir" function and the "help" function to get more infromations 
about the class, but i need to get more information about the class 
structure.

What i also want to know:
>>> variable1 = 10.50
>>> type(variable1)
<type 'float'>

Is there a way to tell python that it use antoher class than float for float, 
like myfloat? Its just a "tell-me-what-is-possible".

Sample:
>>> variable1 = 10.50
>>> type(variable1)
<type 'myfloat'>

Kind Regards,
