Actually you''re wrong, e is a number, e^x is not a function, exp(x) is.
You can define a^(p/q) where a is a positive real number and p and q are integers, q!=0. The only continuous function F(x) from R to R such that F(p/q)=a^(p/q) can be called a^x.
Where do you see a problem with using e^x instead of exp(x)? They are the exact same thing, as far as I know.
