    I am sorry, but I am having trouble reading your handwriting. Does your link say

    f:x\longmapsto x\left\lfloor\frac{1}{x}\right\rfloor


    f:x\longmapsto (-1)^{\lfloor x^2\rfloor}

    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 \min \Pi x mean?
