cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used to calculate a whole range of scientific functions including sin, cos, tan, arctan, arcsin, arccos, sinh, cosh, tanh, arctanh, log, exp, square root a

基于CORDIC算法计算反正切函数。输入横坐标纵坐标及迭代次数，输出角度及弧度值；附CORDIC英文文档说明-atan function based in CORDIC algorithm

判断点和线段之间的关系，包括点在线段的上，点在线段的延长线，反向延长线，点在线段外四种情况-Judge the relationship between the point and line, including the point on the line, in line at the extension of reverse extension cord, and so on.
