I am sorry, but I am having trouble reading your handwriting. Does your link say
$\displaystyle f:x\longmapsto x\left\lfloor\frac{1}{x}\right\rfloor$
$\displaystyle f:x\longmapsto (-1)^{\lfloor x^2\rfloor}$
$\displaystyle f:x\longmapsto \left\{ \begin{array}{rcl} \min \Pi x & \mbox{if} & x\in\mathbb{Q}\\ 0 & \mbox{if} & x\not\in\mathbb{Q}\end{array}\right.$
What does $\displaystyle \min \Pi x$ mean?
