Hello, I am using Mathematica 7.0.2 and playing a bit with an expression analyzed in the following paper: http://www.loria.fr/~zimmerma/papers/cise.pdf I tried many constructions with N and SetPrecision and can't get Mathematica to output the correct result (I am not very experienced with Mathematica). Here is the expression : 173746*Sin[10^22]+94228*Log[17.1]-78487*Exp[0.42] The correct result should be -1.341818958*10^-12 but even forcing each term with N and a very large number, I am still not getting this value at all. Any help will be appreciated. Thanks in advance ; best regards, -- Damien Wyart
