AnglesThere is no type angle in either the rational or the floating point kernel. There are, however, several functions related to angles. In particular, two vectorsv1
and v2 can be compared by the angle which
they form with the positive x-axis. The corresponding function is
int compare_by_angle(VECTOR v1, VECTOR v2); We use the notation VECTOR to indicate that the algorithm works both for vectors and rat_vectors. (More information on
