GEOMETRY application - a problem

[parisse]

Indeed, the equation is rewritten differently and that raised an undef which was not correctly handled by the bisection solver. I fixed the source code.
By the way, for the geometry app, you can also report with commandlines to help me reproduce the problem:
GA:=plotfunc((1/2)^x);GB:=plotfunc(-x^2+3);GC:=inter(GA,GB);coordinates(GC)
