Hi! I wrote:
I'll push a patch for the exp function and for doc/powerlaws.tex.
Well, I didn't push it yet because it turns out that it interferes in surprising ways with mul::eval(). We used to have exp(x)/exp(x) -> 1 but that doesn't work any more because exp(x)^(-1) evaluates to exp(-x) first, resulting in exp(x)/exp(x) -> exp(x)*exp(-x). :-( Unless somebody comes up with a convincing idea how to fix eval() in the presence of pow(exp(x),a) -> exp(a*x) I'm not going to apply this patch.
