RIF can do this: sage: x = RIF(0.33333333333333333333333333333333333) sage: x.simplest_rational() 1/3
More generally, if you know a number to a certain precision: sage: x = RIF(0.33333) sage: y = x + RIF(-1,1)/1e3 # Add error term sage: y.simplest_rational() 1/3 -- You received this message because you are subscribed to the Google Groups "sage-support" group.
