"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.

WebMay 8, 2014 · If the vectors were 2D (a1,a2) & (b1,b2) the angle would be atan2 (b2,b1)-atan2 (a2,a1) the angle being positive as the x axis rotates towards the y axis. The only problem case is if either of the vectors is 0,0 which is indeterminate (x,0) and (0,y) are OK. Webk. By convention, the range of the Fortran ATAN2(Y,X)functionisdeﬁnedtobe [ , ]. This corresponds to the mapping of rotation angles to direction angles in (6a) and number of rotations, k, in (6c). Algorithm developers must explicitly save and restore the number of rotations, k, needed to reconstruct a rotation angle, , from a direction angle, .
