Any built-in function for smallest positive floating point number?

Hello everybody,

Is somebody aware of built-in Python's function that would return a  
value for smallest positive double precision floating point number  
(analogous to 'realmin' in Matlab). Python has built-in sys.maxint  
but I could not find anything for float.

Any help would be greatly appreciated.
