IsNotZero()

bool ON_3fPoint::IsNotZero

(

)

const

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

IsUnset()

bool ON_3fPoint::IsUnset

(

)

const

Returns: True if any coordinate is ON_UNSET_FLOAT or ON_UNSET_POSITIVE_FLOAT

IsValid()

bool ON_3fPoint::IsValid

(

)

const

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

IsZero()

bool ON_3fPoint::IsZero

(

)

const

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