I'm doing a series expansion of complicated expressions using Maple. How can I limit the number of terms, and not the order of the series? To be more precise, I need the series up to x^2, but when I ask for series(expr,x,3) I get terms of x^(2.5) which I don't need. How can I get rid of them without dropping the x^2 terms? series(expr,x,2) truncates them.

Thanks a lot to whomever can help!
