What is the difference between atan and atan2 in C++?

In computing and mathematics, the function atan2 is the 2-argument arctangent. By definition, $${\displaystyle \theta =\operatorname {atan2} (y,x)}$$ is the angle measure (in radians, with $${\displaystyle -\pi <\theta \leq \pi }$$) between the positive $${\displaystyle x}$$-axis and the ray from the origin to the point See more The ordinary single-argument arctangent function only returns angle measures in the interval $${\displaystyle {\left[-{\tfrac {1}{2}}\pi ,+{\tfrac {1}{2}}\pi \right]},}$$ and when invoking it to find the angle measure between the x-axis … See more As the function atan2 is a function of two variables, it has two partial derivatives. At points where these derivatives exist, atan2 is, except for a … See more The $${\displaystyle \mathrm {atan2} }$$ function was originally designed for the convention in pure mathematics that can be termed east … See more The realization of the function differs from one computer language to another: • In Microsoft Excel, OpenOffice.org Calc, LibreOffice Calc, Google Spreadsheets, iWork Numbers, … See more The function atan2 computes the principal value of the argument function applied to the complex number x + i y. That is, atan2(y, x) = Pr arg(x + i y) = Arg(x + i y). The argument could be changed by an arbitrary multiple of 2π (corresponding to a complete turn … See more Sums of $${\displaystyle \operatorname {atan2} }$$ may be collapsed into a single operation according to the following identity ...provided that The proof involves … See more • hypot See more Webatan 和 atan2 区别： 1：参数的填写方式不同； 2：atan2 的优点在于如果 x2-x1等于0 依然可以计算，但是atan函数就会导致程序出错； methodist kirby breast centerWebAtrium Health Carolinas Medical Center. 1000 Blythe Blvd. Charlotte, NC 28203.
