Both CForm and FortranForm will do what you illustrate: In[1]:= CForm[0.1+0.2] Out[1]//CForm= 0.30000000000000004 In[2]:= FortranForm[0.1+0.2] Out[2]//FortranForm= 0.30000000000000004 On Thursday, March 27, 2014 5:00:45 AM UTC-4, Alan wrote: > I would like to illustrate some limitations with floating point calculations.
