The C function atan2, and most other computer implementations, are designed to reduce the effort of transforming cartesian to polar coordinates and so always define atan2(0, 0). On implementations without signed zero , or when given positive zero arguments, it is normally defined as 0. See more 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 The 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 and an arbitrary vector in the 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 The realization of the function differs from one computer language to another: • In Microsoft Excel, OpenOffice.org Calc, LibreOffice Calc, Google Spreadsheets, iWork Numbers, and ANSI SQL:2008 standard, the 2-argument arctangent function has the … 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) = … 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 constant, equal to arctan(y/x). Hence … See more The $${\displaystyle \mathrm {atan2} }$$ function was originally designed for the convention in pure mathematics that can be termed east-counterclockwise. In practical … See more WebPopular answers (1) The atan function simply computes the inverse tangens of a value. The atan2 function takes two values (y and x).
