Hello ! Don't consider it as a problem! The computer works in basis 2. So for him : liste = Table[x, {x, -0.1, 0, 0.02}]; You can see the liste in basis 2 : BaseForm[liste, 2] And you will see that the last number, you expect to be 0, is -1*2^(-58), which is -3.46945 x 10^(-18). If you don't want to see this details we could consider as enjoying, use Chop: In[19]:= Chop[liste] Out[19]= {-0.1, -0.08, -0.060000000000000005, -0.04000000000000001, -0.020000000000000004, 0} Regards F.Jaccard -----Message d'origine----- De : leptonic [mailto:leptonic at gmx.ch] Envoyé : mardi, 6. juin 2006 12:28 À : mathgroup at smc.vnet.net Objet : [heur] [mg66988] Table through zero...strange Hello, When i type in Mathematica (version 4) Table[x, {x, -0.1, 0, 0.02}] it gives me {-0.1, -0.08, -0.06, -0.04, -0.02, -3.46945 x 10-18]} but for example Table[x, {x, -0.1, 0, 0.05}] will give a reasonable {-0.1, -0.05, 0.}. Probably a very stupid question but i can't figure out why the zero makes problem. Thanks for any help.
