By definition, is the angle measure (in radians, with ) between the positive -axis and the ray from the origin to the point in the Cartesian plane. Equivalently, is the argument (also called phase or angle) of the complex number The function first appeared in the programming language Fortran in 1961. It was originally intended to return a correct and unambiguous value for the angle \u03B8 in converting from Cartesian coordinates (x, y) to polar coordinates (r, \u03B8). If and , then and"@en ,

	dbo:abstract	"In computing and mathematics, the function atan2 is the 2-argument arctangent. By definition, is the angle measure (in radians, with ) between the positive -axis and the ray from the origin to the point in the Cartesian plane. Equivalently, is the argument (also called phase or angle) of the complex number The function first appeared in the programming language Fortran in 1961. It was originally intended to return a correct and unambiguous value for the angle \u03B8 in converting from Cartesian coordinates (x, y) to polar coordinates (r, \u03B8). If and , then and If x > 0, the desired angle measure is However, when x < 0, the angle is diametrically opposite the desired angle, and \u00B1\u03C0 (a half turn) must be added to place the point in the correct quadrant. Using the function does away with this correction, simplifying code and mathematical formulas."@en ,

Elle est au moins aussi ancienne que le langage de programmation Fortran et on la trouve maintenant dans la plupart des autres langages. En termes math\u00E9matiques, atan2 retourne la valeur principale de la fonction argument appliqu\u00E9e au nombre complexe . Soit . Le r\u00E9sultat pourrait varier de 2\u03C0 sans aucun impact sur l'angle, mais pour garantir son unicit\u00E9, on utilise la valeur principale dans l'intervalle ]\u2013\u03C0 ,\u03C0], soit . La fonction atan2 est utilis\u00E9e dans beaucoup d'applications impliquant des vecteurs de l'espace euclidien, comme pour trouver la direction d'un point \u00E0 un autre. Une des utilisations principales est la conversion des matrices de rotation en angles d'Euler, pour faire pivoter des repr\u00E9sentations graphiques informatiques. Dans certains langages informatiques, l'ordre des param\u00E8tres est invers\u00E9, ou bien la fonction est d\u00E9nomm\u00E9e diff\u00E9remment. Sur les calculatrices scientifiques, le r\u00E9sultat de la fonction est souvent issu de la conversion des coordonn\u00E9es rectangulaires (x, y) en coordonn\u00E9es polaires."@fr ,

		"Die mathematische Funktion arctan2, auch atan2, ist eine Erweiterung der inversen Winkelfunktion Arkustangens und wie diese eine Umkehrfunktion der Winkelfunktion Tangens. Sie nimmt zwei reelle Zahlen als Argumente, im Gegensatz zum normalen Arkustangens, welcher nur eine reelle Zahl zum Argument hat. Damit hat sie gen\u00FCgend Information, um den Funktionswert in einem Wertebereich von (also allen vier Quadranten) ausgeben zu k\u00F6nnen, und muss sich nicht (wie der normale Arkustangens) auf zwei Quadranten beschr\u00E4nken. Der volle Wertebereich wird h\u00E4ufig ben\u00F6tigt, beispielsweise bei der Umrechnung ebener kartesischer Koordinaten in Polarkoordinaten: wenn der Funktion die beiden kartesischen Koordinaten als Argumente gegeben werden, erh\u00E4lt man den Polarwinkel , der sich im richtigen Quadranten befindet, d. h. der die Beziehungen und mit erf\u00FCllt. Ein mathematisch n\u00FCtzlicher Zusatzeffekt ist, dass Winkel, bei denen der Tangens eine Polstelle hat, n\u00E4mlich die Winkel durch ganz normale reelle Koordinaten spezifiziert werden k\u00F6nnen, n\u00E4mlich durch anstatt Das kommt von der Definitionsmenge der Funktion der \u201Egelochten\u201C Ebene, welche mit einer Gruppenstruktur versehen werden kann, die isomorph ist zur multiplikativen Gruppe der komplexen Zahlen ohne die Null.
