float limits

[Alexandre Fayolle]

Hi,

Is there a way of knowing what the value of the smallest positive float
available on a given machine from within python? A bit like sys.maxint, 
but for mindouble. Similarly, I'd like to know the value of the biggest
positive float, maxfloat. If the solution is portable, that's all the better.

TIA
