The routine finds the midpoint of two points A, B, or of a segment seg.

For a detailed description of the midpoint C, use the routine detail (i.e., detail(C))

The command with(geometry,midpoint) allows the use of the abbreviated form of this command.

$\mathrm{with}\left(\mathrm{geometry}\right)\:$

$\mathrm{point}\left(A\,0\,0\right),\mathrm{point}\left(B\,2\,0\right)\:$

$\mathrm{midpoint}\left(\mathrm{C1}\,A\,B\right)$

$\mathrm{C1}$

$\mathrm{coordinates}\left(\mathrm{C1}\right)$

$\left[1\,0\right]$

$\mathrm{segment}\left(\mathrm{seg}\,\left[A\,B\right]\right)\:$

$\mathrm{midpoint}\left(\mathrm{C2}\,\mathrm{seg}\right)\:$

$\mathrm{detail}\left(\mathrm{C2}\right)$

$\begin{array}{ll}\text{name of the object}& \mathrm{C2}\\ \text{form of the object}& \mathrm{point2d}\\ \text{coordinates of the point}& \left[1\,0\right]\end{array}$
