Question: Why does Maple not plot 0 for these two equivalent expressions?

Question:Why does Maple not plot 0 for these two equivalent expressions?

In the following workbook, I defined two equivalent one variable functions and plot their difference.

I'm surprised to see that the difference is not 0 between 55 and 60. But when I computed the respective function's values at these points, the difference is 0.

assume(n, integer, n > 0)

``

f := proc (n) options operator, arrow; 2^(n+10) end proc

proc (n) options operator, arrow; 2^(n+10) end proc

 (1)

g := proc (n) options operator, arrow; 1024*2^n end proc

proc (n) options operator, arrow; 1024*2^n end proc

 (2)

g(n)-f(n)

1024*2^n-2^(n+10)
