Compare()

static int ON_2fPoint::Compare ( const ON_2fPoint &  lhs, const ON_2fPoint &  rhs  )

static

Description: A well ordered dictionary compare function that is nan aware and can be used for robust sorting.

)

const

IsNotZero()

bool ON_2fPoint::IsNotZero

(

)

const

Returns: true if at lease one coordinate is not zero and no coordinates are unset or nans.

IsUnset()

bool ON_2fPoint::IsUnset

(

)

const

Returns: True if any coordinate is ON_UNSET_FLOAT or ON_UNSET_POSITIVE_FLOAT

IsValid()

bool ON_2fPoint::IsValid

(

)

const

Returns: False if any coordinate is ON_UNSET_FLOAT, ON_UNSET_POSITIVE_FLOAT, nan, or infinite. True, otherwise.

IsZero()

bool ON_2fPoint::IsZero

(

)

const

Returns: true if all coordinates are not zero and no coordinates are nans. false otherwise.
