Is there more than one meaning of the notation "f(x)=[x]"?
In my real analysis textbook there is a question that says:
Decide whether [tex]f(x)=[x][/tex] is bounded above or below on the interval [tex][0,a][/tex] where [tex]a[/tex] is arbitrary, and whether the function takes on it's maximum or minimum value within that same interval.
This question is very straightforward, assuming [tex][x]=x[/tex]. But if that is the case, then the choice of notation is very strange.
Is there another way to interpret the notation's meaning?
