SmallFract Type

The SmallFract type is derived from the low-order word of a fixed integer. The Color Picker Manager uses SmallFract values to save memory and to be compatible with the Color QuickDraw RGBColor structure. You can use the Fix2SmallFract function (page 2-56) to convert a fixed integer to a SmallFract value. You can use the SmallFract2Fix function (page 2-56) to convert a SmallFract value to a fixed integer.

typedef unsigned short SmallFract;/* unsigned fraction between 0 and 
                              1 */
enum {MaxSmallFract = 0x0000FFFF};/* maximum small fract value, 
                              as long */
