integral problem with floor() function
I wanted to verify eulers summation formula, therefore I had to evalute the integral
Integral(f'(x) (x - floor(x)), 1, N)f(x) is defined to 1/x; N is an integer-slider - as you can see by the attached worksheet.
Until N=9 the above integral evaluates correctly (unapproved!) - when the slider switches to 10 or greater the integral is undefined!
What happens here? Any idea or a bug in "integral"?
