Suppose that I have a number $n$ with many decimal digits of precision. What is the code to use to get Mathematica to recognize possible closed-form expressions for that number?

Try Rationalize. Providing more info / examples would be useful, – Yves Klett Oct 13 '14 at 19:20

I often use the PSLQ Algorithm, you find it here: http://mathworld.wolfram.com/PSLQAlgorithm.html – mgamer Oct 13 '14 at 20:26
Could enter it as a Wolfram|Alpha query. Not sure how well that will fare though. – Daniel Lichtblau Oct 14 '14 at 01:02

As @belisarius notes, you're looking for a Mathematica version of Plouffe's inverter (that's what we used to call the link belisarius provides). – Oct 14 '14 at 16:06
I don't understand why this one got 4 close votes so far. This functionality could be included in Mma. – Dr. belisarius Oct 14 '14 at 16:12
@Dr.belisarius Did you vote to reopen? Perhaps an upgrade to the question would help? – Mr.Wizard Feb 09 '16 at 08:18
