It would never have occurred to me either. But the program I wrote that translates the problems from Mathematica to Maple syntax, translates expressions of the form E^z to exp(1)^z. This is because for some inexplicable reason Maple does not define a constant for the base of the natural logarithms, but does for the imaginary unit and pi. Go figure...
