I want to know is there any function in Mathematica that suggests a simple irrational number combination for decimal one?
For example, if I give 0.804738 then I get
(Sqrt + 1)/3.
1.301290284568573 = π/(Sqrt + 1).
It seems for the first example
RootApproximant gives the correct answer but for the second its answer is not useful at all.
