5. A little difference between the atan function and the atan2 function

Introduction: atan and atan2 are arctangent functions. For example: there are two points point(x1,y1), and point(x2,y2); then the angle calculation method of the slope formed by these two points is: floatangle = atan( ( y2-y1)/(x2-x1) ); or float angle = atan2( y2-y1, x2-x1); The difference between atan and atan2: 1: The parameter filling method is different

6. javascript atan2() Calculate the angle from the y). This function has two parameters. The first parameter specifies the X coordinate of the point, and the second parameter specifies the Y coordinate of the point. Note the order of the parameters of this function. The Y coordinate is passed before the X coordinate. This article explains to you the basic syntax and usage examples of the atan2 function. Coders who need it can refer to it.
