SQRT
Finds the square root.
If the argument is negative, the result is 0. The judgement will be NG.
SQRT (argument)
DIST
• Finds the distance between two points (the center of gravity and the center of the model).
DIST (first_position_X, first_position_Y, second_position_X, second_position_Y )
Example: Finding the distance between the centers of gravity of region 0 and region 1
DIST (R0.X,R0.Y,R1.X,R1.Y)
The following calculation is performed internally.
• Finds the length of a perpendicular line from point (x,y) to line ax + by + c = 0.
DIST (X_coordinate_of_point, Y_coordinate_of_point, coefficient_a_of_line, coefficient_b_of_line,
coefficient_c_of_line)
