I would be happy to introduce a short-cut alias for numerical_approx, e.g., N() or n() or ??. You can try out a few by doing this: sage: import sage.calculus.calculus sage: sage.calculus.calculus.SymbolicExpression.N = sage.calculus.calculus.SymbolicExpression.numerical_approx # all one line sage: a = sin(2) + pi + cos(2/3) sage: a.N() 4.83677734119242 Something simple like a.N() might be quite reasonable as a shortcut for a.numerical_approx(), and would be very simple to implement (just one line of code in an appropriate place).
