Datan2 fortran
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 …

WebIntrinsic functions that are Sun extensions of the ANSI FORTRAN 77 standard are marked with @. Intrinsic functions have generic and specific names when they accept arguments of more than one data type. In general, the generic name returns a value with the same data type as its argument. However, there are exceptions such as the type conversion ... WebMar 24, 2024 · You must compare the tolerance to the magnitude of serie. The Taylor series of sin includes negative terms, and the first negative term is causing your loop to exit (on the second one, every time). The tolerance you set is actually 0. 10** (-15) contains only integers, so the answer is evaluated as an integer. Use 10.** (15), or better yet 1.e-15.

WebATAN2. — Arctangent function. ATAN2 (Y, X) computes the arctangent of the complex number X + i Y. The type shall be REAL. The type and kind type parameter shall be the same as Y. If Y is zero, then X must be nonzero. The return value has the same type and kind type parameter as Y.
