Good morning Mathematica users, Can anyone tell me, please, which of a),b) or c) is wrong : a) <MathematicaHelp> <quote> N[expr] is equivalent to N[expr, MachinePrecision]. </quote> </MathematicaHelp> b) In[1]:=N[Exp[Sqrt[163 ]Pi] - 6403203] Out[1]=256. c) In[2]:=N[Exp[Sqrt[163 ]Pi] - 6403203,$MachinePrecision] Out[2]=743.9999999999993 ? Thank you
