NAMEal_set_mouse_wheel_precision - Allegro 5 API SYNOPSIS
DESCRIPTIONSets the precision of the mouse wheel (the z and w coordinates). This precision manifests itself as a multiplier on the dz and dw fields in mouse events. It also affects the z and w fields of events and ALLEGRO_MOUSE_STATE(3), but not in a simple way if you alter the precision often, so it is suggested to reset those axes to 0 when you change precision. Setting this to a high value allows you to detect small changes in those two axes for some high precision mice. A flexible way of using this precision is to set it to a high value (120 is likely sufficient for most, if not all, mice) and use a floating point dz and dw like so:
Precision is set to 1 by default. It is impossible to set it to a lower precision than that. SINCE5.1.10 SEE ALSOal_get_mouse_wheel_precision(3)
