Please look at the picture:

A function defined with "if" can not be integreated. "int" does not like "if" . Could they like each other?

And here is some odd behaviour.

As Greg pointed out, something is wrong.

It seems that the direct calculation of the expression which includes relational operation will be OK. I tried it directly and the transformed form as well (yellow tooltip).

Plotting and calling the defined function containing relational operators will go wrong sometimes (plotting, calling or both). I can not see the pattern.
Here is another text example.

It seems I was wrong. Here is the example where the summation with relational operation fails:

Additionally:
[MATH]x←10[/MATH]
[MATH]sum((k^2*(k≤x));k;0;10)=1[/MATH]

Bug with boolean operators fixed:


You can check this fix here: Alpha: SMath Studio 0.85.3578 (18 October 2009).

Thanks Andrey

The Xcas plugin will be very welcome. I hope the desktop version will come soon.
