    Question type: Mathematical calculation
    Solution:
          24*arctan1/8+8*arctan1/57+4*arctan1/239
        =24*0.785398/8+8*arctan1/57+4*arctan1/239
        =24*0.785398/8+8*0.785398/57+4*arctan1/239
        =24*0.785398/8+8*0.785398/57+4*0.785398/239
        =18.849552/8+8*0.785398/57+4*0.785398/239
        =2.356194+8*0.785398/57+4*0.785398/239
        =2.356194+6.283184/57+4*0.785398/239
        =2.356194+0.110231+4*0.785398/239
        =2.356194+0.110231+3.141592/239
        =2.356194+0.110231+0.013145
        =2.466425+0.013145
        =2.47957
    Answer:24*arctan1/8+8*arctan1/57+4*arctan1/239=2.47957
