A Simple Calculus Exercise

I see the expression "x/2 - floor(x/2)" and automatically read it as "the part of x/2 to the right of the decimal point".

Also called "fractional part", which makes the symmetry a bit more simply obvious.

The tricky part of the problem isn't calculus, it's in a bit of algebra that often isn't emphasized in school.
