Hi
I would like to work with sets that are real intervals or
combinations of them : mainly intersection and union.
Example :
[0,1] intersection with [0.5,pi]
Using the Sage Reference Manual 4.1.1, I was able to do that :
sage: A=Set(RealField())
sage: sqrt(2) in A
True
How to create an interval from this point ?
Have a good day
Laurent
