AdaptableBinaryFunction class: Point_2
\( \times\) Point_2
\( \rightarrow\) bool
.
It returns true
, iff the angle of the direction corresponding to the first argument with respect to the positive \( x\)-axis is less than the angle of the direction corresponding to the second argument.
AdaptableUnaryFunction class: Point_2
\( \rightarrow\) FT
.
Max_coordinate(p)
returns the coordinate of p
with largest absolute value.
AdaptableBinaryFunction class: Point_2
\( \times\) FT
\( \rightarrow\) Point_2
.
Scale(p,k)
returns the point that results from scaling the vector corresponding to p
by a factor of k
.
AdaptableBinaryFunction class: Point_2
\( \times\) Point_2
\( \rightarrow\) Point_2
.
It returns the point that results from adding the vectors corresponding to both arguments.
