DM42 News

I have observed a strange behavior on my DM42. Using the numerical integration application I just checked it for integrating cos(x) from 0 to Pi. As soon as you ask for an accuracy better than 0.1 the time spent for integratingis very long. In fact I have had to sop the integration before end. If you change the domain of integration with such a small quantity as 10^-10 either on zero side or on pi then the convergence is way faster even for a very good accuracy.
I have checked the behavior of Free42 on Windows and Android. The behavior is similar: takes way longer if the domain is exactly 0,Pi. The problem appears only on the decimal version. The binary just works fine. On Windows the integration
ends up slowly but it ends. I’m puzzled. It seems to be related with the use of the decimal library.

If somebody has an idea? Is it a bug or a feature ;-)
