If the Hilbert curve maps the interval [0,1] onto the unit square, is there a formula that tells us where a given point $x \in [0,1]$ will be taken?
EDIT: For example, it seems intuitive that $0$ is mapped to $(0,0)$, $1$ is mapped to $(0,1)$, and $\frac{1}{2}$ is mapped to $(\frac{1}{2},\frac{1}{2})$, ...
