thanks for the help. Yes, i read the user docs for "earlier, faster, thriftier, smaller ..." or a permutation of this, but i do not _really_ remember from my university time what strict functions are. Is by strict meant as in Formal OO that a function is trict iff its result is _|_ iff any of its arguments is _|_ ?
Yes, that's it. In your code, you know that the values are needed eventually; hence, there is no need to expend energy on suspending some of the computations. Moreover, you get a more efficient data representation.
I will try to use
data Genauigkeit = Absolut {wert, intervall :: !Double} | Intervall !Double
is that what you meant?
Yes. Good luck, Manuel
