Yes, but by setting flag 2 on the HP 50g I can use e purely symbolically if I want to. For example, on the HP 50g, I can create a symbolic matrix [['a','b'],['c','e']], and it will display as a 2x2 matrix with symbolic elements a,b,c,e. I can then enter it on the stack and type <alpha> D E T Enter (determinant) and the result shown will be a*e-c*b.
Furthermore, once I have created this matrix with e as a symbol, it will remain so in the matrix even if I clear flag 2, such the determinant will still evaluate to a*e-c*b, even though e entered directly into the stack will now display numerically as 2.7183...
