The function $f$ in the question can be written as $f(x)= (x +1/2)-\lfloor x+1/2 \rfloor $

comment Congruence generalization
Exactly, I could write that, but I wanted a simpler notation. I find very natural to write thinhs like that and generalize algebra in modules. For example (3,5 mod 2 := 2,5). I guess something worked on this before.
