Question: Floating number after laplace(expr, t, s)

Hello all,



As in title I am really bothered with result in floating number obtained from laplace(expr, t, s).

I have a target to laplace and the laplace() gives me result with floating numbers.

(ex. laplace(diff(diff(f(t),t), t), t, s) = laplace(s^2. * laplace(f(t), t, s) : the period after 2 is annoying)


How can I avoid or do some conversions to kill the periods?



Best regards,
