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  xval;
          CPU_INT16S  zres;


                    xval = -101;
          zres =  DEF_ABS(xval);
