Guessing "exact" values


"Another computer algebra system" has a function, identify(), which 
attempts to guess the exact expression that evaluates to a particular 
numerical value.

Example:

In[1]:= N[3Pi+3/2,10]

Out[1]= 10.92477796

 > identify(10.92477796);
                                   3
                                   - + 3 Pi
                                   2

Is there a package with similar functionality for Mathematica?
