WebATAN2 (Y, X) calcule la valeur principale de la fonction argument du nombre complexe X + i Y . Cette fonction peut être utilisée pour transformer des coordonnées cartésiennes en coordonnées polaires et permet de déterminer l'angle dans le bon quadrant. Standard: Fortran 77 et versions ultérieures Class: Elemental function Syntax: WebReturn value: The return value has the same type and kind type parameter as Y.It is the principle value of the complex number X + i Y. If X is nonzero, then it lies in the range -\pi \le \arccos (x) \leq \pi. The sign is positive if Y is positive. If Y is zero, then the return value is zero if X is positive and \pi if X is negative. Finally, if X is zero, then the magnitude of the …
