   opps,  You see, I mixed it up above. I meant the otherway   
   around. If expression is symbolic then   
   Sympy.exp() is the one to call, otherwise, it is   
   SciPy.exp().   
      
   >>> from sympy import symbols, Rational   
   >>> from sympy.functions import exp as sympyExp   
   >>> x=Rational(1/2)   
   >>> sympyExp(x)   
      
        exp(1/2)   
      
   >>> from scipy import *   
   >>> exp(x)
