Quoting Gabriel Dos Reis <address@hidden>:


Here is the result from Maxima:

In Axiom version of  1/17/2005

1.4^2  comes out as 1.96

1.96 - 1.4^2  comes out as  0.7 E -20

I don't know if this counts as unexpected to a 5th grader, but does a
5th grader even know about "E" scientific notation?


What's his point?
