integral competition HP50g vs. DM42

[peacecalc]

Hello ttw,

I cannot answer this, but I guess the two machines use at least a similar algorithmus.
The manuals of these calcs told us: the integration routine doesn't use the left and right limit of the integration interval. The algorithmus can be a kind of gaussian quadrature, because that one doesn't use the limits on the left and right side.

Romberg and other method use the limits of the integration aera.

But maybe I'm wrong.
