Description: A well ordered dictionary compare function that is nan aware and can be used for robust sorting.
float ON_4fPoint::EuclideanX | ( | ) | const |
Returns: ON_UNSET_VALUE, if x or w is ON_UNSET_VALUE or ON_UNSET_POSITIVE_VALUE and neither x nor w is a nan. x/w, otherwise Remarks: If w is 0.0 or nan, the result will be a nan.
float ON_4fPoint::EuclideanY | ( | ) | const |
Returns: ON_UNSET_VALUE, if y or w is ON_UNSET_VALUE or ON_UNSET_POSITIVE_VALUE and neither y nor w is a nan. y/w, otherwise Remarks: If w is 0.0 or nan, the result will be a nan.
float ON_4fPoint::EuclideanZ | ( | ) | const |
Returns: ON_UNSET_VALUE, if z or w is ON_UNSET_VALUE or ON_UNSET_POSITIVE_VALUE and neither z nor w is a nan. z/w, otherwise Remarks: If w is 0.0 or nan, the result will be a nan.
bool ON_4fPoint::IsUnset | ( | ) | const |
Returns: True if any coordinate is ON_UNSET_FLOAT or ON_UNSET_POSITIVE_FLOAT
bool ON_4fPoint::IsValid | ( | ) | const |
Returns: False if any coordinate is ON_UNSET_FLOAT, ON_UNSET_POSITIVE_FLOAT, nan, or infinite. True, otherwise.
