处理步骤解析

1.首先定义一条直线

RowA1 := 255

ColumnA1 := 10

RowA2 := 255

ColumnA2 := 501

dev_set_color ('black')

disp_line (WindowID, RowA1, ColumnA1, RowA2, ColumnA2)

2.再定义一个点

RowB1 := 255

ColumnB1 := 255

3.进行一个360次的循环，得到另外一条线，计算两条线之间的夹角

for i := 1 to 360 by 1

RowB2 := 255 + sin(rad(i)) * 200

ColumnB2 := 255 + cos(rad(i)) * 200

disp_line (WindowID, RowB1, ColumnB1, RowB2, ColumnB2)

angle_ll (RowA1, ColumnA1, RowA2, ColumnA2, RowB1, ColumnB1, RowB2, ColumnB2, Angle)

endfor

测试代码

dev_close_window ()
dev_open_window (0, 0, 512, 512, 'white', WindowID)
RowA1 := 255
ColumnA1 := 10
RowA2 := 255
ColumnA2 := 501
dev_set_color ('black')
disp_line (WindowID, RowA1, ColumnA1, RowA2, ColumnA2)
RowB1 := 255
ColumnB1 := 255
for i := 1 to 360 by 1
    RowB2 := 255 + sin(rad(i)) * 200
    ColumnB2 := 255 + cos(rad(i)) * 200
    disp_line (WindowID, RowB1, ColumnB1, RowB2, ColumnB2)
    angle_ll (RowA1, ColumnA1, RowA2, ColumnA2, RowB1, ColumnB1, RowB2, ColumnB2, Angle)
