value of data (binary floating point) stored in D0 and D1 is

The angle (in radians) is calculated by the COS

operation ([1]).

The value in radians is converted into the value in

degrees ([2]).

The angle expressed in the binary floating point (real

number) is converted into an integer (binary) ([3]).

The angle expressed in integer (binary) is output to

the display unit ([4]).
