Basics
IsAllNonPositive – This method returns true if all properties are not positive.
IndexDouble3 idx3 = new IndexDouble3(3.0, -5.0, -7.0);
bool af = idx3.IsAllNonPositive();
// result for af is false
IndexDouble3 idx3 = new IndexDouble3(-3.0, -5.0, -7.0);
bool af = idx3.IsAllNonPositive();
// result for af is true
IsAllNonZero – This method returns true if all of the properties are not equal to 0.
IndexDouble3 idx3 = new IndexDouble3(0.0, 0.0, 0.0);
bool af = idx3.IsAllNonZero();
// result for af is false
IndexDouble3 idx3 = new IndexDouble3(-3.0, -5.0, 7.0);
bool af = idx3.IsAllNonZero();
// result for af is true
IsAllZero – This method returns true if all property values are equal to 0.
IndexDouble3 idx3 = new IndexDouble3(3.0, 0.0, 0.0);
bool af = idx3.IsAllZero();
// result for af is false
IndexDouble3 idx3 = new IndexDouble3(0.0, 0.0, 0.0);
bool af = idx3.IsAllZero();
// result for af is true
Max – This method returns an Index made of the maximum value of each property.
IndexDouble3 idx_1 = new IndexDouble3(3.0, 10.0, 7.0);
IndexDouble3 idx_2 = new IndexDouble3(1.0, 15.0, 6.0);
IndexDouble3 idx_max = IndexDouble3.Max(idx_1, idx_2);
// idx_max value is (3.0, 15.0, 7.0)
