ABSTRACT:
A linear value is converted to an integer equivalent, where a triangle OAB is considered, consisting of the origin 0 (0,0), point A (L,Y) and point B (L,0), and the conversion is accomplished by figuring out the y coordinate value Z of point P, whose x coordinate value is X, out of integral lattice points positioned in the vicinity of side OA in the xy coordinate system. In this method, the y coordinate value Z is figured out by the following core calculation function: f(X,Y) satisfying prescribed conditions: Z=f(X,Y)wherein 0≦X≦L, 0≦Y≦L, X,Y: integers, andL=2s−1, S≧1, S: an integer.
