is_concyclic_R16P Function

  1. vecfor_R16P.F90
  2. vecfor_R16P
  3. is_concyclic_R16P

public elemental function is_concyclic_R16P(self, pt1, pt2, pt3, tolerance) result(is_concyclic_)

Return true if the point is concyclic with other three given points.

Based on Ptolemy’s Theorem.

 type(vector_R16P) :: pt(0:3)

 pt(0) = -1 * ey_R16P
 pt(1) =  1 * ex_R16P
 pt(2) =  1 * ey_R16P
 pt(3) = -1 * ex_R16P
 print "(L1)", pt(0)%is_concyclic(pt1=pt(1), pt2=pt(2), pt3=pt(3))

 type(vector_R16P) :: pt(0:3)

 pt(0) = -1 * ey_R16P
 pt(1) =  1 * ex_R16P
 pt(2) =  1 * ey_R16P
 pt(3) = -1 * ex_R16P
 print "(L1)", is_concyclic_R16P(pt(0), pt1=pt(1), pt2=pt(2), pt3=pt(3))
