The example below illustrates why Mathematica's display rules for approximate numbers are very confusing for students. Should this be considered a user-interface bug? If not, why not? In any case, can the default display be changed to something more familiar from spreadsheets and other computing languages?
Thanks,

In[217]:= tv = TimeValue[1, 0.04, 3]
tv == 1.124864
tv == 1.12486

Out[217]= 1.12486

Out[218]= True

Out[219]= False
