addHash unsigned int LVecBase2d::add_hash(unsigned int hash) const; Description: Adds the vector into the running hash. |
addToCell void LVecBase2d::add_to_cell(int i, double value); These next functions add to an existing value. i.e. foo.set_x(foo.get_x() + value) These are useful to reduce overhead in scripting languages: Description: |

almostEqual bool LVecBase2d::almost_equal(LVecBase2d const &other, double threshold) const; Description: Returns true if two vectors are memberwise equal within a specified tolerance. Description: Returns true if two vectors are memberwise equal within a default tolerance based on the numeric type. |
compareTo int LVecBase2d::compare_to(LVecBase2d const &other) const; Description: This flavor of compare_to uses a default threshold value based on the numeric type.
