#### 17.3.6 Remarks

The resolution of a dial is about 0.2 degrees, i.e., there are only about 2000 steps per 360 degrees and, depending on the size of the dial, it is typically less.

The dial is always drawn with a circular box. If you specify a `FL_UP_BOX`, a `FL_OVAL3D_UPBOX` will be used.

See the demo programs `ldial.c`, `ndial.c` and `fdial.c` for examples of the use of dials.
