Ideally, DEF_ABS() should be defined in the custom mathematics library, lib_math.*. However, to maintain backwards compatibility with previously-released modules, DEF_ABS() is still defined in lib_def.h .

Example Usage

          CPU_INT16S  val;
          CPU_INT16S  res;


          val = -101;
          res =  DEF_ABS(val);
