Atan vs atan2 cpp
WebATAN2 (a,b) equals ATAN (b/a), except that a can equal 0 in ATAN2. If both x_num and y_num are 0, ATAN2 returns the #DIV/0! error value. To express the arctangent in degrees, multiply the result by 180/PI ( ) or use the DEGREES function. Example Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. Webatan2(y, x) The data type of the y and x parameters can be double, float, or long double. The return value has the range of [-π, π]. A negative value is returned if the y parameter is …
